Armacell Tundra Foam 1-1/8" Open Cell Backer Rod 300'/Bag

1-1/8" Diameter, Open Cell Polyurethane Foam, Solid, Sealant Backer Rod (300' per Bag/600' per Sleeve)

Backer rods are round or flat flexible lengths of foam that are used as a "backing" in joints or cracks to help control the amount of sealant used or the depth of the sealant in the gap. Some applications require closed-cell back-up material that won't absorb moisture, others seal best with open cell foam that is highly compressible and will fill irregular joints more evenly. No matter your application, Armacell offers the most extensive collection of backup materials and the largest range of sizes on the market. Combined with outstanding service, prompt delivery and competitive pricing, Armacell is the only one-stop source for all your backer rod requirements. Armacell's FillPro ® backer rods are sold through Sealant and Accessories distributors in the US and Canada.
