Frequently Asked Questions

What adhesive is this screen tube compatible with?

This Opti-Mesh screen tube is specifically designed for use with the SET-3G epoxy adhesive formulation. Screen tubes are formula-specific, and epoxy screen tubes must only be used with SET-3G. Using the wrong screen tube with a different adhesive formulation can compromise anchor performance.

Why are screen tubes necessary for hollow block or brick applications?

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 screen tube contains the adhesive within the drilled hole, allowing it to properly cure around the rod and form a reliable bond even where there is no solid material to retain the adhesive on its own.

What prevents the screen tube from falling into an over-drilled hole?

The Opti-Mesh screen tube features flanges specifically designed to prevent the screen tube from slipping into over-drilled holes, keeping it properly positioned during adhesive injection and rod installation.

What rod diameter and hole size does this screen tube accommodate?

This screen tube is designed for a 1/2 in. rod diameter and requires a 3/4 in. hole size. The integral cap centers the rod during installation and also displays the appropriate drill bit and rod diameter for easy reference on the job site.
