Standard Wheeley Bars are designed to be used on hard flat surfaces only. The optional large-wheel upgrade, with great care in maneuvering and ideal conditions, 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.

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.
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 from 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.

Selecting the Right Wheeley Bars
When deciding which Wheeley Bar model to purchase, there are several things to consider. These include:
- Type of equipment you will be transporting
- Tip-to-tip distance of the tripod feet
- Total weight of the equipment to be transported
- Type of 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).
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).
The Medium Size Universal Wheeley Bars are for small, lighter telescopes like a standard C8 that weighs less than 70 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.
The standard 5″ wheels work fine to move over concrete with cracks or seams (like sidewalks and driveways) or rough cobblestone-like surfaces. 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?
What Size Wheels Should I Purchase?
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.
|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.|
“Your dolly’s fit the need perfectly. Good workmanship. My iOptron mounts love theses (as well as my back).” (R. R. 08/03/2017)
“The Wheeley Bars with the large 5/8″ screws along with the heavier mount made all the difference. My scope setup is now solid as a rock. Thank you so much for helping me with the advice. I never would have believed the mount and screws would have made that much difference but it does. Thanks for making a superior mobile setup. It is well worth the money!” (F. G. 07/2017)
“…BTW, my wife and I love and appreciate JMI products (especially the Wheeley Bars—makes it easier for my wife to move her 10-inch dobbie!” (M. H. 03/2017)
“…thanks so much for your voice mail, conversation and amazing customer service. If you guys ever need a comment, endorsement, etc., please contact me. (J. H. 03/2017)
“…that is more than fair and very much appreciated. I guess that thoughtfulness is why JMI products and support are so widely respected.” (H. C. 03/03/2017)
“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.)
