The new Pro Series Backer Installation Tool is a must have tool for installing the new Pro Series Backers. This aluminum tool is designed to hold the single Pro Series Backers while installing the studs. The tool allows you to safely apply pressure to the backer and also keep the backer oriented properly for optimum results. While this tool is not designed specifically for the Pro Series Double Backers, it does help when applying pressure to start both studs in the backer.
