Frequently Asked Questions

What adhesive is this screen tube compatible with?

This acrylic screen tube is specifically designed for use with Simpson Strong-Tie AT-XP adhesive. Acrylic screen tubes must be used with AT-XP, as screen tubes are designed for a specific adhesive type and are not interchangeable across different adhesive formulas.

What rod diameter does the AWS373P screen tube accommodate?

The AWS373P is designed for a 3/8 in. rod diameter, and requires a 9/16 in. drilled hole to properly seat the screen tube.

Why is a screen tube necessary for adhesive anchoring in hollow block or brick?

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 and allows it to properly cure around the rod, ensuring a strong, reliable anchor in these challenging substrates.

How does the Opti-Mesh design improve performance over standard plastic or steel screen tubes?

The Opti-Mesh screen tube features a formula-specific woven mesh design that controls the flow of adhesive out of the screen, and an open-mesh collar that allows extra adhesive flow in hollow block applications. This combination provides superior performance compared to both steel screen tubes and competitive plastic screen tubes, while retaining the economical advantage of a plastic construction.
