On each side of your door opening the side rails mount to each door jamb. The bottom door
rollers roll up on each side rail. The door rolls up on these side rails, providing a safe guide for
the door rollers as the door opens and closes. Our side rails are heavy 1/4" thick angle iron
for good solid backing.
