Astragals and Meeting Stile seals are used to seal the clearance gap between a pair of doors. The astragal is installed vertically on the face of either side of a pair of doors. Astragals can be made of molded rubber and or nylon. Astragals can used on all types of interior or exterior doors.
Door bottom sweeps are surface applied to the bottom face of a door. They are commonly used on the exterior of outswing doors. Door sweeps/channels help with keeping out the cold, heat, wind, insects, and rodents. Door sweep channels are available in several styles with materials based on your application. The inserts for door sweeps allow customers to select from vinyl, neoprene, nylon brush and pile depending on the application.
