Sweep GaSket Replacement
1. Determine which sweep gasket your walk-in has:
a. Old sweep gasket held in with screws (go to #2)
b. New style held in by integral dart (go to #5 and skip #6).
2. Remove screws that retain the old style gasket (if no screws
hold in gasket, skip to #5) and remove gasket.
3. With old sweep gasket removed, determine if door gasket
length needs to be cut to accommodate new style door sweep
by placing sweep gasket into position. If the sweep can be
positioned so the dart on the back of the gasket aligns with the
slot in gasket retainer of the door without interference from the
door gasket, proceed to #5 and skip #4 and #6.
4. If door gasket interferes with new floor sweep, pull 6 to 8
inches of the door gasket out from gasket retainer on both
ends of gasket.
5. Install sweep gasket starting at one end, insert dart-shaped
projection into retainer slot and using a rubber mallet, drive
dart into the retainer slot.
6. With sweep gasket in place, mark the length of the door
gasket. Cut door gasket to butt up against the sweep gasket.
Seal the ends of door gasket, if necessary, with silicon.
