Special-Lite® Astragals are designed to cover the clearance gap between door pairs, acting as a weather seal, minimizing noise, reducing smoke infiltration in case of a fire, and further increasing energy-efficiency of the entrance. Our astragals also increase security by reducing an intruder’s ability to force open the doors. Available as a flat bar or with a vinyl weather seal, Special-Lite Astragals can be ordered for doors with a radius stile or a bevel stile.

Astragals are available in any of the anodized and painted finish colors we offer or can be matched to any custom color.


To ensure weather sealing on pairs of doors, ask for our radius stile profile with an integral adjustable astragal on the active leaf.
