Litaibai 40-Foot Kerf Door Weather Stripping for Grooves | Fits 1/8-Inch Grooves, 1/4–1/2-Inch Gaps | Brown

Meet the Litaibai 40-Foot Kerf Door Weather Stripping

Designed to adapt to a range of door frames, this long weather strip provides flexible sealing for interior and exterior doors. Its 5/32 inch spine fits about a 1/8 inch groove and it works with door gaps from 1/4 inch to 1/2 inch. To ensure a precise fit, measure your groove and gap before purchasing.

Crafted for durability, the kerf seal uses a rigid PVC flange that slides into the groove for a secure hold. A tear-resistant PE cover shields a high-resilience PU foam core, helping the seal stay flexible and effective across temperatures and seasons.
