Short Description

FillPro Open Cell is an ideal non-gassing backer rod used to control sealant and caulking depth and create a back stop to allow proper sealant tooling and configuration, to allow proper sealant airing and to yield a proper bond break between backup material and sealant. Limiting the depth of the sealant prevents excessive use, saving on caulk or sealant. Compressibility is ideal for non-uniform joint sizes.
