About This Tool
Description
The Backer Rod Insertion Tool is a professional-grade hand tool designed to seat foam backer rod into caulk joints quickly, cleanly, and at a precise, consistent depth — without puncturing or compressing the rod unevenly. It eliminates guesswork during installation and ensures the sealant applied on top forms the correct hourglass profile for maximum flexibility and long-term bond performance.
