** Your CGE mount may require Large Size Universal Wheeley Bars depending on the tip-to-tip distance.  It may also require the 10" Pneumatic Large Wheel Upgrade (to lower the mount to an acceptable height).

NOTE

Do not use the standard Medium Wheeley Bars for 12" or larger SCTs (even if the mount is listed above) as these telescopes are too heavy for this product.  Check out the HEAVY DUTY Version below.

The picture at left shows the Medium Size Universal Wheeley Bars with the standard 2-3/8" wheels.  The optional 5" Large Wheels are also shown for size comparison.

This picture shows the Medium Size Universal Wheeley Bars under a Meade Standard Field Tripod.  The Wheeley Bars adjust for the legs of your tripod mount (within specific limits).  They are designed to be used with the legs fully retracted to keep the center of gravity low and allow the telescope to be moved through doors

HEAVY DUTY Medium Size Universal Wheeley Bars

Astro-Physics 6" Eagle Adjustable Folding Pier mount

The HEAVY DUTY Version is designed for heavier equipment with the same footprint as the standard Medium Wheeley Bars and the heavier construction of the Large Wheeley Bars.  In other words, they are like Large Size Wheeley Bars with short legs (the same length as the Medium Size Wheeley Bars).

Because of the increased weight with the narrow width, there will be a greater risk due to the high center of gravity.  The equipment will need to be strapped down to the Wheeley Bars and, as with all Wheeley Bars, JMI will not be responsible for equipment tipping over.

Maximum Load:  300 lbs
Adjusts to fit tripods with tip-to-tip distance from 33" to 43"
See doorway measurements for more dimensions.

Tip receptacle is 2-3/4" I.D.
Raises most mounts 3-1/2" off the ground with standard wheels (5" for Astro-Physics pier mounts)
Wheel diameter is 2-3/8"  (optional 5" and 10" wheels are available)

Fully locking 5" diameter polyurethane wheels to replace the standard 2-3/8" hard-rubber wheels on Universal-Style Wheeley Bars (both standard and custom versions).  With these wheels, the Wheeley Bars will raise the mount 6-3/8" off the ground.

For wheel size recommendations, please see What Size Wheels Should I Purchase?

Upgrade at Time of Purchase Only*, Part Number TPWLWUPG
Purchased Separately**, Part Number TPWLW

NOTES

* If you simply wish to purchase the Wheeley bars with 5" wheels rather than 2-3/8" wheels, pick the "upgrade at time of purchase" option (part number TPWLWUPG).  This price is cheaper because the small wheels are essential "traded in" toward the price of the larger wheels.

** If you wish to replace your 2-3/8" wheels with 5" wheels after the original purchase, use the "purchase separately" option (part number TPWLW).  You can only replace your small wheels with the large wheels if your current wheels are attached with bolts (current manufacturing method) rather than rivets (very old manufacturing method).  With this "aftermarket" option, YOU will be removing the original wheels and installing the 5" wheels.  The necessary longer leveling bolts are included.  (JMI will not accept returns of used small wheels.)

The first picture at left is of JMI Universal Wheeley Bars with the prototype 10" Pneumatic Large Wheel Upgrade, optional Battery Pack Holder and an Orion Dynamo Pro 17 Power Station (not available from JMI, see our 21 Ah Power PAC battery pack).  The dual inboard wheels on each rear "axle" help keep a narrow profile.  The product also includes a pull handle.

The second pictures shows what is included in the 10" Pneumatic Large Wheel Upgrade as a separate purchase.

Is this an AFTER-MARKET Upgrade (PURCHASED SEPARATELY) for
PRE-OCTOBER 2013 Large or Heavy Duty Medium Wheeley Bars?

If you are purchasing the Large 10" Pneumatic Wheel Upgrade for Large Size Universal Wheeley Bars or HEAVY DUTY Medium Size Universal Wheeley Bars purchased before October 2013, please let us know that you need the Long Mounting Bracket.  You can do so by entering, "LONG MOUNTING BRACKET" in the Comments field in our shopping cart.  (If you are purchasing the upgrade at the same time you are purchasing the Wheeley Bars, you do NOT need to add this note.)

You can verify the need for the Long Mounting  Bracket by measuring the Threaded Leveling Screw Guide (Long Nut) which holds the leveling screw (see picture below).  Units built before October 2013 used a longer guide/nut which measures about 2-3/8" and requires the Long Mounting Bracket.  Current guide/nut length (which does NOT require the longer bracket) is about 1-5/8".

What are Wheeley Bars?

Do you wish you had an easy way to move your tripod or pier mounted telescope from garage to patio or driveway?  Wheeley Bars (telescope wheels/dolly) were created for just that purpose.  The sturdy base with locking wheels and leveling bolts allows you to easily move, lock, level and use the complete telescope assembly.  And best of all, you don't have to disconnect and reconnect all the electrical and computer cabling.

Standard Wheeley Bars are designed to be used on hard flat surfaces only.  With the optional large-wheel upgrade, great care in maneuvering and ideal conditions, they can be used on grass, dirt and gravel surfaces.  Wheeley Bars are generally designed to be used with the tripod legs almost fully retracted to reduce the overall width.

A Word of Warning:  The heavier the telescope mounted on the Wheeley Bars, the more careful one must be in moving the complete system by pulling or pushing below the center of gravity.  JMI is not responsible for incorrect loading or operation.


What is Tip-to-Tip Distance?

To be sure that your tripod or pier will fit a particular Wheeley Bar product, it may be necessary to verify the tip-to-tip distance of the mount.  Usually, this measurement is made with the legs of a tripod fully retracted (the shortest length) and spread out completely.  Alternately, you can measure at your preferred viewing height, but be sure to allow for the height of the Wheeley Bars (listed with each product).  The tip-to-tip distance is the measurement from the outside edge of the end of a tripod leg or pier foot (where it touches the ground) to the outside edge of another tripod leg or pier foot as illustrated below.

         

Here are some examples of different types of tripods and piers and where to measure.

For Custom Wheeley Bars, to be sure that your mount will fit into the receptacles, we also need to know leg or foot diameter and tip style.  For instance, on the mounts shown above (numbered from left to right), the following applies:

Mount
Number
Diameter
Needed
Tip
Style
1 Leg Tube
2 Foot Flat Foot
3 Leg Rounded Tip
4 Leg Pointed Tip
5 Foot

Flat Foot


Doorway Measurements

We often get questions regarding the width of our Wheeley Bars to determine if they will fit through a particular doorway.  The following information should help in making that determination.  The following dimensions do not apply to Wheeley Bars that have been upgraded with 10" large wheels.  For Universal Wheeley Bars with the 10" Large Wheel Upgrade the doorway width must be three (3)  inches wider than the tip-to-tip distance.

There are three basic measurements as noted above.  The maximum width (X) is measured in a similar fashion as the tip-to-tip distance except that the measurement is made to the outside corner of the legs or leveling screws (typically about 3" wider than the tip-to-tip measurement of a pointed tip tripod mount).  The minimum measurement (N) is from the end of one leg to the inside measurement on the opposite side.  This would help in determining the narrowest door that the Wheeley Bars could possibly be maneuvered through.  A third measurement (W) is in between the other two and gives the width as measured form the end of one leg to the outside measurement of the opposite side.  The diagrams below illustrate the three measurements.

   

The illustration on the left shows the Universal Wheeley Bars turned so they can be pushed through the doorway based on the NORMAL width (W) without having to do any special maneuvering.  The second illustration shows the Universal Wheeley Bars being maneuvered by twisting them through the doorway based on the absolute MINIMUM dimension (N).  The third illustration shows the Wheeley Bars being blocked from moving though a doorway because they are positioned such that the MAXIMUM profile (X) is being presented.

Universal Wheeley Bars are called Universal because they are made to be adjustable to handle various sizes of mounts.  This means that the measurement we have been talking about can vary depending on the in-out adjustment of the Wheeley Bar legs.  The table below shows the minimum and maximum for the different widths indicated by the variable W, N and X.

What Size Wheels Should I Purchase?

The small 2-3/8" hard-rubber wheels are good for flat hard surfaces with no cracks or grooves.  For hard surfaces, such as concrete sidewalks, with seams or cracks, the 5" polyurethane wheels are best.  The large 10" all-terrain pneumatic rubber-tire wheels are designed for field use on rough surfaces such as grass, dirt and gravel.  However, great care must be taken in maneuvering on these surfaces, particularly when wet, because the wheels may sink below the surface.  We do not recommend using Wheeley Bars on these surfaces under adverse conditions, especially if you have a very heavy telescope.
 


Selecting the Right Wheeley Bars

When deciding on which Wheeley Bars to purchase, there are several things to consider.  These include:

The TYPE OF EQUIPMENT you will be transporting
The TIP-TO-TIP DISTANCE of the tripod feet
The TOTAL WEIGHT of the equipment to be transported
The SURFACE you will be moving the equipment over

TYPE OF EQUIPMENT
Dobsonian telescopes should use one of our Dob-style Wheeley Bars based on which Dob you have.  Telescopes with a tripod should use one of the Universal-style Wheeley Bars.  The size will depend on the size and weight of the telescope equipment (see below).

TIP-TO-TIP DISTANCE
The Universal-style Wheeley Bars show a minimum and maximum tip-to-tip distance for the tripod legs.  The best way to measure the tip-to-tip distance is to set your telescope up the way you would normally use it then measure the distance between two tripod feet.  Be sure to account for the height the Wheeley Bars will lift your equipment off of the ground.  Compare that measurement with the range shown for each size of Universal Wheeley Bars to match up with the best fit.  Custom Wheeley Bars are available for those that fall outside of all of the listed ranges.  For more information on how to make this measurement, see What is Tip-to-Tip Distance?

If you wish to move your telescope equipment through a doorway, see Doorway Measurements to verify whether you will be able to maneuver your equipment through a particular doorway (based on the size of the Universal Wheeley Bars).

TOTAL WEIGHT
The Medium Size Universal Wheeley Bars are for small, lighter telescopes like a standard C8 that weighs less than 100 pounds.  If you have a telescope with tip-to-tip distance that falls into the Medium range but weighs near or over 100 pounds (total weight of all equipment) you should use the HEAVY DUTY Medium Wheeley Bars since they will support the weight much better.  If you are planning on adding any equipment to your telescope in the future (like cameras, guide scopes, etc.) you should take that weight into consideration.  Heavy Duty Medium, Large and Custom Wheeley Bars can carry up to 300 pounds.  We also carry Extra Large and Max Wheeley Bars for specific very large telescopes.

SURFACE
The standard 2-3/8" wheels work fine if the surface is hard and flat, such as a gymnasium floor or smooth concrete.  If you need to move over concrete with cracks or seams (like sidewalks and driveways) or rough cobblestone-like surfaces, you should get the 5" Wheel Upgrade as these will ride over these surfaces much better without getting stuck.  If moving over grass, dirt or gravel (or you just want a smoother ride) you should use the 10" Pneumatic Wheels.  These wheels will travel over surfaces smoothly and not sink into cracks.  There are times when the 5" wheels can be used on hard dirt, but if the weight of the telescope is more than 100 pounds, the 5" wheels may dig into the upper layer of dirt and become hard to move.  For more information on the composition of the different wheels, see What Size Wheels Should I Purchase?

WARNING
We do not recommend using Wheeley Bars on any surface under adverse conditions, especially if you have a very heavy telescope.  The heavier the telescope mounted on the Wheeley Bars, the more careful one must be in moving the complete system by pulling or pushing below the center of gravity.  JMI is not responsible for incorrect loading or operation.

Customer Comments

"I am absolutely delighted with the [TPWLB12] Wheeley Bars as it makes movement of the telescope around the yard very easy.  For a telescope of this size I would not be able to use it to full advantage without the ability to move it easily both for observation and storage.  Thanks for a great product well worth it's price.  The quality of construction immediately made an impression while I was assembling it for use."  (P. R.  06/2014)

"Got the Wheeley Bars!  Fantastic high-quality product.  Machine work on every part is perfect and there wasn't a single part which I wasn't impressed with the sturdiness of.  Great product!!!!  Thanks."  (J. Z.  05/2014)

"My order for the Heavy Duty Medium Universal Wheeley Bars arrived today and I had to write regarding it because so much about the entire order impressed me.  Let me begin with the packaging itself.  I have not seen an order in many years that was so well packaged....  But the packaging was not the only thing which I was impressed by.  The design and workmanshipo is top notch....  (R. A.  09/2012)

"Just received your large Wheeley Bars and they are exceptionally robust, well-engineered and beautifully made!  They are exactly what I need to get more observing time and less set-up time."  (S. S.)

"I received my Wheeley Bars as ordered, thanks.  I just have to say that this has been the best accessory I have ever bought for my scope hands down.  I'm very pleased indeed.  It makes shifting and setting up my scope a breeze.  Thanks again.  (S. K.)

"Last June I bought your Wheeley Bars for my 16" Meade LightBridge.  Needless to say, they have been fantastic.  I use the scope at least ten times as much now as I did before putting it on the Wheels.  Any time I want to observe, I just wheel it out of the garage and I'm ready within a couple of minutes!  No re-collimating needed!  Contrast that with moving the heavy scope out by hand in three parts, putting it together and re-collimating.  This process had been a real deterrent to using the scope—not to mention disassembling it at night, cold and sleepy.  I had considered spending $$$ on an observatory shelter but using the Wheeley Bars is so much better, and incredibly cost-effective.  But you know all this!  Your simple invention has re-opened the world of astronomy for me.  And my neighbors—any time it's going to be a good star night I send out an email and they come over.  Thanks again."  (T. P. W. Jr.)

"I have received my order [Wheeley Bars].  Your service was very good.  Much better than the servie I have had when purchasing other goods from the USA.  My advice to my fellow Astronomical Society members will be, if you can buy it from JMI, go there first."  (I. G. F-W., Australia)

"[I] Love being able to wheel my telescope in-and-out of the garage on a whim without having to wait for help to move it.  I'm a 5'-2", 53-year-old grandmother who couldn't move the scope without help so this was just the ticket.  Ladies, you'll love it!  Also, you just leave it on there while you star hop.  The handle detaches so you don't fall over it in the dark....  Thanks JMI!!!"  (C. J.)

"I look forward to using my Wheeley Bars with my heavy telescope.  It is sturdy and well made."  (S. B. H.)

"Well, I must say the product was more than I expected.  Great work!!  After years of the electronic stuff I have gone back to a Dob and Your wheelies make it so easy!  Thanks!!"  (J. W.)

"REALLY like my Wheeley....  [My] C-102-HD is happy.  So is my hernia.  <G>"  (P. H.)

"I received a set of your Wheeley Bars....  I put it together this morning with no trouble.  This setup is the cat's meow and the elephant's PJs all rolled (pun intended) into one.  Now I can keep the scope up and easily accessible on a whim as my binocs.  How cool.  Thank so much."  (M. M.)

"I have a Meade 10" LX200GPS on one set of Wheeley Bars and a CGE on another set and absolutely love them.  It isn't just the weight  I can carry the mount in a couple of trips, no problem.  The really huge advantage of the Wheeley Bars is that I can leave the mount/tripod/electrical and computer connections (USB hub, power strip) all attached permanently on the Wheeley Bar setup.  I wheel out, attach one electrical connection (extension cord to the power strip), one computer connection (USB cable to the USB hub) and I am ready to go.  A huge time saver setting up and taking down compared to having to make multiple connections each time.  (D. S.)

"The materials used for the Wheeley Bars is excellent.  They have exceeded my expectations.  Good product."  (D. C. B.)

"The quality of the Wheeley Bars exceeded my expectations!  I assembled them easily and with no problems.  Good Job!"  (S. S.)

"The Wheeley Bars are one of the best products ever introduced to the Amateur Astronomer in history...  Your Wheeley Bars are exceptionally well designed for the price..."  (R. J. G.)


Frequently Asked Questions (FAQ)


Q. How can I be sure that a particular model will fit my tripod mount?
A. First, make sure the legs on your tripod are fully retracted  (i.e. set as short as possible).   Measure the distance from the tip of one leg to the tip of the next.  Compare this distance with the specifications shown for the model designed for your tripod.   The receptacles that accept the tripod legs are designed for the width and style of tips on your tripod legs.

If you do not see your particular model of tripod listed, we may be able to build a custom unit.  You will need to give us specific information on tip-to-tip distance (with legs fully retracted), leg diameter and tip style.
   
Q. Why are the Wheeley Bars designed to be used with the tripod legs fully retracted?
A. For stability and to allow movement of the telescope through a doorway.   In most cases this height will be acceptable for normal use.
   
Q. How do the legs of the tripod fit into the Wheeley Bars?
A. Generally, they rest inside a hole as large as, or larger than, the width of the tripod tip.  Once inserted, you can extend the legs slightly until the tips are snug in their receptacles.
   
Q. How much will the Wheeley Bars elevate my telescope and mount above the ground?
A. That information is given in the description for each model.  Large wheel upgrades include information on how they affect the height.
   
Q. Can I use Wheeley Bars to move my telescope over grass?
A. The original Wheeley Bars were designed for use on hard surfaces only.  Some customers have stated that they are able to use them on grass but we do not recommend it.  Our 5" Large Wheels will work on smooth grass surfaces.  With the 10" Pneumatic Large Wheels, great care in maneuvering and ideal conditions, Wheeley Bars can be used on grass, dirt and gravel surfaces.
   
Q. Can I get information on the wheels used on your Wheeley Bars?
A. The standard hard-rubber wheel is 2-3/8" in diameter and 1-1/8" in width.  An upgrade to large 5" diameter polyurethane wheels is available.   These tow sizes are lockable to keep them from rolling when not using the leveling bolts.  A 10" Pneumatic rubber all-terrain wheel is also available.  See What Size Wheels Should I Purchase?
   
Q. What material are the Wheeley Bars made of?
A. They are made from sturdy steel channel or rectangular tubing covered by durable black-wrinkle paint.   If treated properly, they should last several lifetimes.
