CRL Sof® Rod 1-1/2 in x 6 ft Cut Length Replacement

• Controls sealant depth and functions as an effective bond breaker for long-lasting joints
• Compatible with all cold-applied sealants; avoid use with hot-pour sealants where surface temperatures exceed 160°F (71°C)
• Soft, extruded polyolefin foam with a resilient dual-cell structure allows easy compression during installation

CRL Sof® Rod (SKU: SR112B) is a dual-cell backer rod and advanced sealant backing material that combines open- and closed-cell performance in a single extruded polyolefin product. A continuous length of non-absorbent foam with a resilient internal structure reduces out-gassing and prevents sealant bubbling and failure. Chemically inert, Sof® Rod is designed for compatibility with virtually all known cold-applied sealants, including self-leveling types.

CRL Sof® Rod is available in diameters from 3/8” to 2” (10 to 51 mm).

Temperature Limits:
-45° to 160°F (-43° to 71°C)

Common Applications:
Backer rod for glazing, curtain wall construction, partitions, parking decks, bridge construction, modular home gasketing, and log home chinking.

Size Selection:
Choose a backer rod approximately 25–50% oversized relative to the joint width to ensure a tight fit. Proper size selection controls sealant depth and provides a reliable bond breaker.

Storage:
Store in a well-ventilated area out of direct sunlight. Keep away from heat sources and open flames.
