CRL 1-1/8" Open Cell Backer Rod - 350 Foot Roll

The CRL Open Cell Backer Rod is a versatile and highly compressible polyurethane foam designed for use with both cold-applied and hot-pour sealants.
Its open-cell structure ensures flexibility and adaptability to irregular or damaged joints, eliminating the risk of outgassing when punctured.
Available in diameters from 5/8” to 2” (16 to 51 mm), this backer rod is perfect for high-performance sealants like silicones and urethanes, making it ideal for vertical and horizontal wall joints.
For optimal performance, proper size selection is crucial; the rod should be approximately 50% wider than the joint to ensure a snug fit.
Remember to store the product in a well-ventilated area away from direct sunlight and heat sources.
For installation, follow precise joint preparation and use the recommended tools for a smooth application.
Note that this product is not suitable for horizontal traffic surfaces, and compatibility with sealants should be confirmed with the manufacturer.
