Frequently Asked Questions

What adhesive formulation is the EWS623P screen tube compatible with?

The EWS623P is designed exclusively for use with the ET-3G epoxy adhesive formulation. Screen tubes are designed for a specific adhesive type, and epoxy screen tubes must be used with the ET-3G formulation to ensure proper performance and reliability.

What rod diameter and hole size does the EWS623P accommodate?

The EWS623P is designed for a 5/8 in. rod diameter and requires a 7/8 in. drilled hole size. The integral cap helps center the rod and displays the drill bit and rod diameter for easy reference during installation.

Why should I use an Opti-Mesh screen tube instead of a standard screen tube?

The Opti-Mesh screen tube features a formula-specific woven mesh design that 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 a standard screen, making it superior in performance to both steel screen tubes and competitive plastic screen tubes.

What prevents the EWS623P screen tube from slipping into an over-drilled hole?

The EWS623P features flanges specifically designed to prevent the screen tube from slipping into over-drilled holes. Additionally, the open-mesh collar allows extra adhesive flow in hollow block applications, ensuring consistent and reliable anchor performance in void-containing base materials.
