| These 5" wheels make it easier to move your assembled telescope over rough and uneven ground than the 2-3/8" wheels that normally come with the JMI Medium and Large Universal Wheeley Bar tripod transports. The standard 2-3/8" hard rubber wheels are fine for moving on smooth surfaces such as patios and driveways. However, if your scope must travel across grass, dirt, and gravel, or uneven hard surfaces such as flagstone paving, the larger diameter of these wheels lets you maneuver much more easily on these rough surfaces. You can either specify using these wheels when you first order your Wheeley Bar (versions #WBAR5 or #BWBAR5), or you can order the wheels separately at a somewhat higher cost to upgrade the 2-3/8" wheels on an existing Wheeley Bar. The fully locking 5" polyurethane wheels replace the standard 2-3/8" wheels on all Universal Wheeley Bars. With these wheels, your telescope sits 2-3/4" higher off the ground than with the standard 2-3/8" wheels. Longer leveling bolts are therefore included with the 5" wheel set. You can only replace your existing 2-3/8" wheels with these 5" wheels if the wheels on your Wheeley Bar are attached with bolts (the current method) rather than rivets (very old method). For regular travel over very rough surfaces, consider the Wheeley Bar versions that use a pull handle and six 10" diameter pneumatic wheels (#WBAR10 and #BWBAR10). A word of warning. Care must be taken in maneuvering on rough or uneven natural surfaces, particularly when wet, as even the 5" wheels may sink below the surface and snag unexpectedly. We do not recommend using a Wheeley Bar on rough surfaces under adverse conditions, especially if you have a very heavy telescope. Use care when moving the complete system on smooth surfaces, as well. Be certain the tripod legs are fully and firmly inserted into the Wheeley Bar’s leg receptacles. Pull or push the system only by gripping the telescope tripod below the center of gravity. Do not push the top of the scope to get it moving, particularly on uneven surfaces. Astronomics and JMI are not responsible for incorrect loading or operation.
