Dual Soft Rod Non Gassing Backer Rod
Dual Rod is a soft, flexible compressible, non-gassing backer rod used in expansion and contraction joints to control sealant application. It also helps produce a uniform joint contour will acting as a bond breaker between the backer material and sealant.
Primarily for specialty applications where closed cell/open cell are not satisfactory. Dual Rod is particularly well suited for irregular joints requiring self leveling, flowable sealants.
