Simpson Strong-Tie Opti-Mesh 10 in. Epoxy Adhesive Plastic Screen Tube for 3/8 in. Rod (Model EWS3710P) is engineered to maximize the performance of epoxy adhesive anchors in hollow or void-containing base materials such as hollow block and brick. Designed specifically for use with the ET-3G epoxy formulation, this Opti-Mesh screen tube features a formula-specific woven mesh insert that delivers superior performance compared to both steel screen tubes and competitive plastic screen tubes - combining the economical advantage of a plastic tube with enhanced load capacity.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter
• Flanges prevent the screen tube from slipping into over-drilled holes
• Formula-specific woven mesh design controls flow of adhesive out of the screen
• Uniform coverage of adhesive on the rod results in higher loads than for rods installed with standard screen
• Open-mesh collar allows extra adhesive flow in hollow block applications
• Caution: Screen tubes are designed for a specific adhesive type; epoxy screen tubes must be used with ET-3G formulation

Frequently Asked Questions

What adhesive formulation is the EWS3710P screen tube designed to be used with?

The EWS3710P Opti-Mesh screen tube is designed specifically for use with the ET-3G epoxy formulation. Screen tubes are adhesive-specific, and epoxy screen tubes must only be used with the ET-3G formulation to ensure proper performance.

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 screen tube contains and properly distributes the adhesive around the rod within the hollow cavity, enabling the anchor to achieve its full load capacity.

How does the Opti-Mesh design improve performance compared to standard screen tubes?

The Opti-Mesh screen tube features a formula-specific woven mesh design that precisely controls the flow of adhesive out of the screen. This results in uniform coverage of adhesive on the rod, which produces higher loads than rods installed with a standard screen. It also outperforms both steel screen tubes and competitive plastic screen tubes.

What prevents the EWS3710P from slipping into an over-drilled hole during installation?

The EWS3710P is equipped with flanges that prevent the screen tube from slipping into over-drilled holes. Additionally, the integral cap centers the rod and displays the required drill bit and rod diameter to help ensure proper installation from the start.
