illbruck PR102 Backer Rod

This closed-cell backer rod is suitable for professional backing of construction movement joints, connection joints and profiled glass seals in interior and exterior applications. Its water-repellent structure helps achieve the correct joint depth and geometry in accordance with the sealant manufacturer’s specifications. The flexible round profile is easy to insert into cavities and joints and provides a consistent limitation of the sealant depth.

Application
Insert the backer rod into the joint without stretching it and push it in until the required joint dimensions are achieved. When joining several pieces, lightly compress the ends. Movement joints must be designed and installed in accordance with DIN 18540.
