50 Pcs R Panel Foam Outside Closure Strips 3 Feet Long - Weatherproof Seal for Metal Roofing & Siding, Perfect for Home & Commercial Building Protection

This listing is for 50 pieces R-Panel Outer foam closure strips. 35-1/2" wide 1" deep. 12OCS closures are flexible with exceptional strength and uniform compression. 12OCS panel closures are also very lightweight and easy to handle / install. 12OCS resists high temperatures and its configuration virtually eliminates moisture absorption and vapor transmission problems. Rust is no problem either - even at building bases and eaves. 12OCS will not crack, shrink, or dry out as do conventional closures. Use 12OCS where chemical resistance is required.
