Frequently Asked Questions

Which adhesive formulation is this screen tube compatible with?

This Opti-Mesh screen tube is designed specifically for use with the ET-3G epoxy adhesive formulation. Epoxy screen tubes must be used with the ET-3G formulation. Screen tubes are designed for a specific adhesive type, so always verify compatibility before installation.

What rod diameter and hole size is the EWS7513P designed for?

The EWS7513P is designed for a 3/4 in. rod diameter and requires a 1 in. hole size, with an overall length of 13 in.

How does the Opti-Mesh screen tube prevent installation errors in over-drilled holes?

The screen tube features flanges that prevent it from slipping into over-drilled holes, and an integral cap that centers the rod while displaying the correct drill bit and rod diameter - helping to ensure proper placement and consistent results.

Why use the Opti-Mesh screen tube instead of a standard screen tube?

The formula-specific woven mesh design controls the flow of adhesive out of the screen, resulting in uniform coverage of adhesive on the rod. This uniform coverage produces higher loads than rods installed with standard screen tubes, and the open-mesh collar allows extra adhesive flow in hollow block applications for superior anchoring performance.
