These steel stops snap onto the rail and allow :
to hold a manual garage door in the open position. In this case, lift the door and the axis of the door will roller pass over the rounding of the room. This is sufficient to prevent it from falling back down.
or limit the opening by adding a stop screw to stop the roller.
Compatible with an up-and-over or sectional garage door
