Screens 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 provides the economical advantage of a plastic screen while providing performance comparable to steel screens and better than competitive plastic screens.

Screens are for use in hollow CMU, hollow brick and unreinforced masonry applications.

1. Integral Cap: Serves to center and secure the rod in the screen, while displaying important information such as rod diameter, drill bit diameter and the Simpson sign for easy inspection after installation. The cap also prevents adhesive from running out of the front of the screen.
2. Flanges: Prevents the screen from slipping into over-drilled holes. Allows screen to function in holes that are drilled too deep.
3. Open Mesh Collar: This section of larger mesh allows extra adhesive to flow out of the screen 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.
4. Color Coded, Formula-Specific Mesh: The screen mesh is sized to allow only the right amount of adhesive to flow through the screen to bond with the base material while the balance remains in the screen to bond the rod. Acrylic-Tie screen mesh is white while Epoxy-Tie screen mesh is black
