Shipping Details

Upgrade door protection with this 36" kerf slide-in double bulb weatherstrip door bottom. Designed for standard 1.75" kerf slots, the dual-bulb compression seal blocks drafts, dust, insects, and moisture more effectively than fin-only strips. Built-in rain caps help redirect water away from the threshold, and the strip fills gaps up to 1/2" for improved energy efficiency. Slide into the kerf slot—no adhesives or screws required—and trim to size for a custom fit on entry, patio, or garage doors. Durable rubber and plastic construction ensures long-lasting performance for residential and commercial use.

Measure Kerf Distance

Good, but may not fit some doors. Be sure to measure distance between your kerf, as it fit my metal door perfectly, but not my fiberglass door.
