CRL 3/8" Sof® Rod - 3600 Foot Roll

CRL Sof® Rod is a superior sealant backing material designed to control sealant depth and function as an effective bond breaker.
With compatibility across all cold-applied and hot-pour sealants, this soft and compressible material ensures easy installation.
Its dual-celled structure, combining open and closed cells, prevents out-gassing and sealant failure.
Available in diameters ranging from 3/8” to 2” (10 to 51 mm), the CRL Sof® Rod is ideal for various applications, including glazing and bridge construction.
Ensure proper size selection—oversized by 25-50% of the joint width for optimal performance.
For best results, store in a cool, ventilated area away from direct sunlight and heat sources.
Always follow joint preparation and installation instructions for maximum effectiveness.
Note: Do not use with hot-pour sealants where temperatures exceed 160°F (71°C).
