CRL 1-1/2" Sof® Rod - 6 Foot Cut Length Pieces

CRL Sof® Rod is a premium sealant backing material designed to control sealant depth and function as an effective bond breaker, compatible with both cold-applied and hot-pour sealants.
Its unique dual-celled structure, combining open and closed cells, prevents out-gassing and sealant failures, while its soft material ensures easy compression during installation.
Available in diameters ranging from 3/8" to 2", CRL Sof® Rod is ideal for applications in glazing, curtain wall construction, and more, boasting temperature limits from -45° to 160°F.
For optimal performance, it's crucial to select the correct size, oversizing it by 25-50% wider than the joint, and ensure proper storage away from direct sunlight and heat sources.
