Simpson Strong-Tie makes dispensing adhesives easier than ever by providing a variety of manual and pneumatic tools as well as accessories designed to make dispensing adhesive as efficient as possible. Screen tubes are used in hollow base material applications to contain adhesive around the anchor and prevent it from running into voids. These Simpson Strong-Tie epoxy-adhesive screen tubes are specifically designed to work with ET-HP® adhesive in order to precisely control the amount of adhesive that passes through the mesh. This results in thorough coating and bonding of the rod to the screen tube and base material. 6-in. Steel Epoxy-Adhesive Screen Tube for 3/8-in. Rod (Pack of 150).
