JMI Wheeley Bars – Meade 10/12 Inch Lightbridge creates an easy way to move mounted telescopes to and from observing locations. This is a customized model with four large 10″ all-terrain pneumatic wheels and a tow handle, consisting of a sturdy base with locking wheels and leveling bolts.  Easily move, lock and level the complete telescope assembly from location to location without the need to disconnect and reconnect all the electrical and computer cabling during transport.

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.

Compatible with:

  • Meade LightBridge 10″ / 12″ (Due to variations in foot placement on the 10″ LightBridge, one or more of the feet on the base of the scope may need to be moved in order for this scope to fit)
  • Apertura AD12
  • Orion SkyQuest XT12 / XX12 (Some modification is needed to make the Go-To scopes fit due to placement of four nuts on the azimuth bolt mounting plate (bottom of scope/ground board).
  • Sky-Watcher 12″
  • Zhumell 10″ / 12″
  • Adaptable to other Dobsonians with 26″ Diameter Ground Board. Again, sometimes ground board feet must be moved.

Note: 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.

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).

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.


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?


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.
