Bottom-Mount Weatherstripping

Brush Seal

Also known as door sweeps, this weatherstripping closes the gap between the bottom of the door and the floor.

Brush seals have flexible bristles that fill the gaps in irregular surfaces, such as pitted concrete, to block light, wind, and moisture. Made of nylon, the bristles are durable and long-lasting. They’re also lightweight, so they won’t slow down self-closing doors.

Seals with an anodized aluminum flange are more corrosion resistant than seals with an aluminum flange. The finish won’t tarnish even in harsh weather conditions.

Seals that meet UL 1784 are rated for smoke and draft control.

Bottom-Mount Weatherstripping with Drip Guard

Brush Seal

Stop rain and snow from pooling in your threshold and seeping under the door. This weatherstripping has a drip guard that diverts water away from the seal between the bottom of the door and the floor. Also known as door sweeps.

Brush seals have flexible bristles that fill the gaps in irregular surfaces, such as pitted concrete, to block light, drafts, and moisture. Made of nylon, the bristles are durable and long-lasting. They’re also lightweight, so they won’t slow down self-closing doors.

Self-Adjusting Bottom-Mount Weatherstripping

Mounted with Door Closed

Mounted with Door Open

Brush Seal

Avoid scuffing your floor and reduce wear on your seals—this weatherstripping has a plunger that lowers the seal as the door is closed and raises it as the door is opened. Also known as door sweeps, they close the gap between the bottom of the door and the floor. Weatherstripping can be cut with a saw. Up to 4" can be removed from weatherstripping with a nylon, silicone, or neoprene seal.

Brush seals have flexible filaments that conform to fill gaps. The filaments are nylon for good wear resistance.

Closed seal projection is measured when the door is closed. It does not include how much the seal retracts when the door is open.

Frame-Mount Overhead-Door Weatherstripping

Shown Installed

Brush Seal

Mount this weatherstripping to the sides and top of an overhead door frame to close gaps. The seals are angled, so they press against the door’s surface without blocking its path.

Brush seals have flexible bristles that fill gaps in uneven surfaces, so they stop drafts better than flat seals. Made of nylon, they’re strong, long-lasting, and they stand up to UV light and moisture.

Double-Door Weatherstripping

Seal the space between your double doors.

Brush seals are sold in pairs—one strip for each door. They have flexible bristles that interlace when the doors are closed to block light and sound. However, they’re less weathertight than the other seal types. Made with nylon seals, the bristles are durable and long-lasting. They’re also lightweight, so they won’t keep doors from opening or closing. Anodized aluminum flanges resist corrosion and won’t tarnish even in harsh weather conditions.
