CRL 2" Closed Cell Backer Rod - 6 Foot Cut Length Pieces

The CRL Closed Cell Backer Rod is an essential tool for optimizing sealant application, featuring a flexible polyethylene foam design that ensures precise control over sealant depth and enhances joint design.
With a non-bonding surface, it eliminates the need for an additional bond breaker and is compatible with all cold-applied sealants, helping to improve sealant performance by reducing stress at adhesion points.
Available in diameters ranging from 1/4" to 2" (7 to 50mm), this backer rod is perfect for various applications including curtain walls, construction partitions, and building rehabilitation projects.
Ensure correct sizing, typically 25-50% wider than the joint, for optimal results and store it in a well-ventilated area to maintain product integrity.
