Pemko XG2212-APK773BL Commercial Door Bottom, U-Shaped Shoe, For 1 3/4" Thick Door, 3 11/16" Overall HT, Adjustable Up to 1 1/2 in Gaps, Fire Rated, Mill Finish Aluminum

The Pemko XG2212-APK773BL is a fire-rated commercial door bottom built to seal the gap beneath 1 3/4" thick doors. Its U-shaped shoe design wraps under the door edge and holds a durable insert that presses against the threshold, blocking drafts, light, sound, and smoke transfer. Constructed with a mill finish aluminum housing, this door bottom offers a clean, low-profile appearance while standing up to daily commercial use. With an adjustable range up to 1 1/2" for larger gaps, it accommodates uneven floor conditions and settling frames. It's a reliable choice for offices, schools, healthcare facilities, and other high-traffic buildings where consistent perimeter sealing matters.

Features

• U-shaped shoe design wraps around the bottom edge of the door for a secure seal.
• Fire rated for use on labeled door assemblies.
• Fits standard 1 3/4" thick doors.
• Adjustable to close gaps up to 1 1/2" for uneven floors and thresholds.
• Mill finish aluminum housing resists wear in commercial environments.
• Overall height of 3 11/16" provides ample coverage.

Functional Details

The U-shaped shoe cradles the bottom rail of the door and carries a flexible insert that maintains contact with the floor or threshold. Vertical adjustment lets installers fine-tune the seal against the walking surface, compensating for gaps and irregularities without replacing the unit.
