Simpson Strong-Tie AWS503P - Acrylic Adhesive Screen Tube for AT-XP, 1/2" x 3-1/2"

Screen tubes are vital to the performance of adhesive anchors in base materials that are hollow or contain voids, such as hollow block and brick. The Simpson Strong-Tie Opti-Mesh screen tube with woven mesh insert provides the advantages of a plastic screen tube while providing superior performance to steel screen tubes and competitive plastic screen tubes. Key Features Integral Cap: Serves to center and secure the rod in the screen tube, while displaying important information such as rod diameter, drill bit diameter and the Simpson Strong-Tie “≠” symbol for easy inspection after installation. The cap also prevents adhesive from running out the front of the screen tube. Flanges: Prevent the screen tube from slipping into over-drilled holes. Allow screen tube to function in holes that are drilled too deep. Open-Mesh Collar: This section of larger mesh allows extra adhesive to flow out the screen tube behind the face shell of hollow block applications. The extra “collar” of adhesive increases bearing area and results in higher load capacities in hollow concrete block. Color-Coded, Formula-Specific Mesh: The openings between the woven mesh screen tube strands are sized to allow only the right amount of adhesive to flow through the screen tube to bond with the base material while the balance remains in the screen to bond the rod. Material Plastic Caution Screen tubes are designed for a specific adhesive type
