The 217DV36 door shoe seals the bottom gap on 1.75" thick doors where air infiltration and sound transfer create problems. This U-shaped aluminum profile with vinyl insert mounts to door bottoms and fills gaps up to half an inch. Pemko designed this 36-inch shoe for weatherization applications where you need both air sealing and sound dampening at the door threshold.
The anodized aluminum housing holds a vinyl insert that compresses against the floor or threshold when the door closes. The dark bronze finish matches architectural hardware finishes common in commercial construction. This door shoe handles thermal expansion while maintaining contact with uneven floor surfaces.
