The total length of the Slider Dolly 23W is 24" inches which will allow the carrier platform approximately 15" of linear slide in between both axles.
The width of the axles are 7" from wheel to wheel.
The wheels use high end roller bearings with smooth (roller blade type) rubber wheels.
The axles can be moved to the inner tap to allow for a tighter turning radius. Asles have retractable feet to lock the slider in place when desired.
