Frequently Asked Questions

What adhesive formulation is the EWS376P screen tube compatible with?

The EWS376P is designed specifically for use with the ET-3G epoxy adhesive formulation. Screen tubes are adhesive-specific, and epoxy screen tubes must only be used with the ET-3G formulation to ensure proper performance and load capacity.

What rod diameter and hole size does the EWS376P accommodate?

This screen tube is designed for a 3/8 in. rod diameter and requires a 9/16 in. drilled hole size for proper installation.

Why is a screen tube necessary when using adhesive anchors 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 Opti-Mesh screen tube contains the adhesive and ensures uniform coverage on the rod, which results in higher load performance compared to rods installed with a standard screen.

What design features prevent installation errors with the EWS376P screen tube?

The integral cap centers the rod during installation and clearly displays the required drill bit and rod diameter, reducing guesswork. Additionally, the flanges on the tube prevent it from slipping into over-drilled holes, helping ensure a secure and accurate installation every time.
