Scaffoldmart's tie bar with swivel couple. Use this when you want to secure your scaffold to the wall you are working on. Our tie bar is 36 inches long and has a tab on one end vertically and the other end horizontally. A 5/8 inch hole is pre-drilled in each end to attach the bar with a lag screw to your wall. We recommend using this tie bar every 12 ft.; it literally anchors the tower to the wall. Outriggers on any of our tower packages will no longer be necessary.
