## Description

This universal garage door bottom seal creates a tight barrier between the door and floor to block water, wind-driven rain, snow, dust, dirt, and debris. Made from flexible rubber, it maintains integrity across extreme temperatures ranging from -40°F to 284°F without cracking, drying out, or warping. Its serrated base grips securely on concrete, asphalt, painted, or treated surfaces while anti-slip ridges enhance safety during installation and daily use. The 20 ft. length allows customization for most standard single and double garage doors. Installation requires no special tools just clean the surface, peel the backing, and press firmly into place. It compresses smoothly under the door’s weight to form an effective seal that improves energy efficiency by reducing drafts. The low-profile height of 0.6 in. ensures smooth door operation without binding or resistance. This seal is intended for residential garage doors and functions best when installed on level, dry, and debris-free thresholds.

• Rubber garage door bottom seal blocks water, snow and debris
• Easy to install with peel-and-stick backing; no tools required
• Designed for residential use on level thresholds
