100mm U-Groove Wheel with Mounting Bracket

The gate will run along the pre formed zinc plated track. The top of the track is shaped like a u so it will run perfectly along this edge.

This wheel has a mounting bracket to make installation even easier, it just bots on to the underside of the gate.

If you have lots of heavy traffic it may be a good idea to support the track in some way or support the weight of the vehicles passing over it. An extreme example would be to cut a channel in the floor so that the top of the track is flush with the road surface then the full weight of the vehicles will never reach the track.
