Use the Low Bottom Rail 3 in the following circumstances:
1.The front edge of the door sill is flush with the exterior trim or door frame and there is a minimum of 9/16" (15 mm) clearance from the top of the sill and the deck below B .
2.There is a minimum of 9/16" (15 mm) clearance, but the front edge of the door sill is recessed C . Use a shim or an aftermarket sill extension to extend the sill so it is flush with the exterior trim or door frame.
