Product Overview
The Brixwell 4 inch Closed Cell Backer Rod is designed for use in sealing and joint filling applications where controlled sealant depth and proper backing support are required. Manufactured from closed cell foam, this backer rod resists moisture absorption and provides a firm, consistent backing for caulking and sealant installations.
With a 4 inch diameter and 6 foot stock length, it is suitable for filling large gaps and expansion joints in construction, window, door, and concrete applications. The closed cell structure helps prevent sealant from bonding to the back of the joint, allowing for proper sealant movement and improved performance.
The flexible foam material compresses easily to fit snugly into joints of appropriate size. Always select a diameter slightly larger than the joint width to ensure proper compression and secure placement.
