Fully locking 5" diameter polyurethane wheels to replace the standard 2-3/8" hard rubber wheels on Universal-Style Wheeley Barks (both standard and custom versions). With these wheels, the Wheeley Bars will raise the mount off the ground an additional 2-7/8" more than the standard 2-3/8" wheels.
The large 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.
