Sure-Loc Hardware Sure-Loc Barn Door Track Anti Jump Lock

Once you have your barn door installed on the flat track, you want to make sure it stays there. The way the barn door hangers work, there has to be some clearance to be able to mount your door up on the track. The last thing you want is for that door to bounce off the track when someone suddenly pulls it or stops it. The anti-bump block is mounted at the top of the door. It does not affect the operation of the door but fills the void between the door and the track so that there isn't enough room for the door to bounce off.
