Introducing the GRABO Seam Setter rail system! This attachment is a no-frills rail system that connects two GRABO tools, for users to easily set two materials together. With a metal base plate, you connect the rail system to the GRABO's external anchor points for maximum stability. This seam setter serves the two main purposes installers want, push and pull, and leveling the two materials. This straightforward and durable rail seam setter system allows you to get the job done right.
