Shut It Cantilever Wheel:

With this assembly a wheel can be installed on a rail rather than on a v-track on the ground surface. These installations are ideal when installing a track on the ground is not feasible. Whether it is on a full cantilever gate system or the SHUT IT designed semi and quarter cantilever system, the HardCORE Cantilever Wheel Assembly is a perfect solution for the odd job. 

The 4" (102mm) HardCORE V-Groove Wheel for 11⁄2” (38mm) Gate Frames is designed to be used on a gate with a 11⁄2” (38mm) bottom rail. All HardCORE wheels use SHUT IT’s unique bushing design, which fully utilises the roller bearings.
