Heavy commercial traffic requires regular replacement of vertical door weatherseals. The CRL Commercial Door Astragal is an easy-to-install, easy-to-adjust mill finished extruded aluminum weatherseal that fits millions of existing installed commercial doors. It installs with just a screwdriver and the pre-punched spring tensioners assure fast, easy adjustment to the mating surface. It is similar to, and will retrofit, Kawneer® astragals with a center channel width of 1/2 inch (12.7 millimeter) or more. An exclusive impermeable film barrier effectively stops air infiltration and the 84 inch (2.1 meter) length fits most store fronts. It can also be cut to fit unusual length requirements.
