Tremco 007763 504 3/4' x 1100' Backer Rod

The Tremco 3/4″ x 1100′ Backer Rod is a versatile construction material designed to optimize the application of caulking and sealants in joints and gaps. Made from closed-cell polyethylene foam, it serves as a resilient backstop that controls the depth of sealant application and ensures proper adhesion. The 3/4″ diameter is suitable for filling medium-sized gaps effectively, providing a consistent and uniform seal. With a generous length of 1100 feet per roll, it offers ample coverage for extensive construction projects, including window and door installations, expansion joints, and concrete joints. The use of backer rod enhances the durability and effectiveness of sealants by reducing three-sided adhesion, thus improving the overall performance and longevity of the sealing application.
