CRL B0CBR112 Black 1.5" Open Cell Backer Rod - 200 ft Roll

C.R. Laurence B0CBR112 Black 1-1/2" Open Cell Backer Rod - 200 Foot Roll is an essential tool for achieving optimal sealant performance in construction and repair projects. Designed from soft, round open cell polyurethane foam, this backer rod compresses easily, allowing it to adapt to joint variations without compromising integrity. Its open cell structure eliminates the risk of sealant failure due to out gassing, making it a reliable choice for both new installations and repairs. The B0CBR112 is compatible with all cold-applied sealants, including high-performance silicones and urethanes, and is effective in temperatures ranging from -65°F to 400°F (-54°C to 204°C). Proper installation is crucial; the rod must be oversized by 50% to ensure a snug fit in the joint, controlling the depth of the sealant bead and acting as a bond breaker to prevent adhesion on the bottom side. Packaged for easy unrolling and installation, this backer rod is specifically designed for vertical and horizontal wall joints, though it is not suitable for horizontal traffic joints. For optimal results, ensure joints are clean and dry prior to application. The B0CBR112 is a reliable solution for enhancing the longevity and effectiveness of your sealant applications.
