Genuine Therma-Tru® sills and bottomsweeps help form a tight seal against wind-driven moisture infiltration at the bottom of the door system and help channel moisture away from the home. The sill pan (recommended) adds an extra layer of protection to help keep moisture away from the subfloor.
Available Depths - 5-3/4, 7-3/4
