Closed Cell Backer Rod - 100 ft Roll

The C.R. LAURENCE EF14C CRL 1/4" Closed Cell Backer Rod is a round, flexible, closed-cell polyethylene foam with an exterior "skin" used as a backing and thickness control device for elastomeric and other cold-applied sealants. This Backer Rod becomes an integral part of the joint into which it is installed, and it is available in a range of diameters to accommodate joints from 3/16" to 1-5/8" (5 to 41 mm).

The Backer Rod is designed to limit the depth of the sealant, thereby preventing excessive use of the sealant and promoting proper joint design. Because the sealant will not bond to the "skin" of the rod, it can stretch and recover with joint movement, with minimal stress being put on the points of adhesion to the substrate.

The EF14C version of the CRL Closed Cell Backer Rod is a 100" roll that does not come on a spool. It is compatible with all cold-applied sealants and allows for easy control of the sealant application thickness. Additionally, the Backer Rod does not require a bond breaker, as it will not adhere to the sealants.
