CRL 5/8" Open Cell Backer Rod - 1400 Foot Roll

The CRL Open Cell Backer Rod is an innovative solution for controlling sealant depth and acting as an effective bond breaker, compatible with both cold-applied and hot-pour sealants.
Made from soft, compressible polyurethane foam, it adapts easily to irregular joints without succumbing to dynamic movement.
Available in diameters ranging from 5/8” to 2” (16 to 51 mm), this open-cell rod eliminates the risk of outgassing, making it perfect for high-performance sealants like silicones and urethanes.
Ideal for vertical and horizontal wall joints, the rod is not recommended for horizontal traffic surfaces.
For optimal performance, ensure proper size selection and follow storage and joint preparation guidelines.
