Garage Door Bottom Seal Kit

Garage door bottom seal kit that blocks dust, drafts, and rain at the floor.

Slide a fresh U-shape rubber gasket into the aluminum retainer track and reclaim a tight seal across the threshold. The kit ships with 16 feet of weatherstripping, enough to dress a standard single-car door, plus the aluminum channel that holds it flush against the concrete. Color is black, so it disappears against most door bottoms.

Why this garage door bottom seal kit works

• Weather block: Stops driven rain, fall leaves, and winter drafts from entering at the floor line.
• U-shape O-ring profile: Compresses against uneven concrete to fill gaps along the sill.
• Aluminum track retainer: Holds the gasket straight and resists corrosion over seasons of use.
• 16 ft (4.8 m) length: Covers a typical single-bay residential garage door in one run.
• Pest and pollen barrier: Closes the gap mice, spiders, and seed pods slip through.
