The 217APK36 door shoe seals the bottom of 1.75-inch thick doors against air infiltration, sound transmission, and light gaps. This U-shaped aluminum profile mounts to door bottoms and accommodates gaps up to half an inch. Pemko designed this weatherstrip for exterior doors where energy efficiency and environmental separation matter.
The mill finish anodized aluminum housing holds a PemkoPrene gasket insert that compresses against the floor or threshold. Custom cutting ensures proper fit across the full 36-inch door width. The shoe protects door edges from wear while maintaining consistent contact pressure.
