Key specifications
- Self-adhesive sponge rubber seal — closes the gap around a door or window with no screws or track
- Black neoprene rubber, made in the USA — a solid rubber seal rather than an open foam strip
- Closed-Cell Sponge Rubber — it squashes down to follow an uneven gap and springs back each time
- 3/8" (9.5mm) wide — measure the flat face you are sealing against so the strip sits fully on it
- 1/8" (3.2mm) deep — it takes up a small gap without stopping the door from closing and latching
- Built-in 3M brand PSA tape — peel the liner, press it into place, and the strip is on in minutes
- Rolls from 8 ft to 300 ft — one roll for a single door or a long roll for a building, then trim

About the brand
Embassy
Embassy is Homebuilders Hardware's premium residential and architectural brand. Designed for builders and homeowners who demand top-tier finish quality, durability, and a refined aesthetic. Backed by our Product Guarantee.
Self-adhesive weatherstripping with a closed cell sponge rubber (neoprene) seal, 3/8″ wide, backed with 3M pressure-sensitive adhesive. It sticks to the door stop or frame and seals against the door face.
Why self-adhesive
It is the weatherstripping for a frame with no kerf slot and no appetite for drilling — an older building, a rented space, or a door you want sealed this afternoon. Peel the backing, press it on, and it is done. Nothing is cut and nothing is permanent.
What to check before you order
The surface. Adhesive needs a clean, dry, smooth frame to hold. It will not stay on rough masonry, flaking paint or a damp surface. Wipe the frame down first.
The length. Available 24" to 144", cut to length. Measure the full run you need to seal, not just the door width.
- Self-Adhesive weatherstripping comes as a single roll. You can trim to specifications before applying.
