The 221DV36 door shoe installs on commercial door bottoms to seal gaps up to 0.5 inches while protecting against impact damage. This U-shaped aluminum casing extends 3 inches up both faces of 1.75-inch doors, making it ideal for high-traffic areas where doors take abuse from carts, equipment, and foot traffic. The vinyl insert provides weatherization and energy efficiency by blocking air infiltration at the door bottom.
Pemko designed this door shoe for restoration projects where door bottoms are damaged but the door frame remains sound. The combination kick plate and seal restores function without full door replacement. The dark bronze anodized finish matches most commercial hardware while the flexible vinyl insert maintains contact across uneven floors.

This door shoe meets UL 10C fire door assembly standards and UL 1784 air leakage requirements. It also complies with ANSI/BHMA A156.22 door gasketing standards and ASTM E283 air infiltration testing protocols.
Fire-rated installations require careful attention to UL 10C listing compatibility with the complete door assembly. For buildings with stringent egress requirements, review NFPA 101 Life Safety Code provisions to ensure weatherization components don't interfere with required opening forces.
