The Simpson Opti-Mesh 6 in. Epoxy Adhesive Plastic Screen Tube for 3/8 in. Rod is purpose-built to maximize adhesive anchor performance in hollow or void-containing base materials such as hollow block and brick. Simpson Strong-Tie engineered this screen tube with a formula-specific woven mesh insert that delivers the cost efficiency of a plastic screen tube while providing superior performance compared to steel screen tubes and competitive plastic screen tubes - making it a reliable solution for contractors and installers who demand consistent, high-load results. Designed exclusively for use with the ET-3G epoxy adhesive formulation, this Opti-Mesh screen tube ensures precise adhesive containment and uniform rod coverage in every application.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - eliminates guesswork during installation, reducing the risk of misalignment and on-site errors.
• Flanges prevent the screen tube from slipping into over-drilled holes - keeps the tube correctly positioned even when hole depth varies, protecting installation integrity.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - ensures the right amount of ET-3G epoxy is distributed where it is needed for a consistent, dependable bond.
• Uniform coverage of adhesive on the rod results in higher loads than for rods installed with standard screen - delivers greater anchoring strength, giving installers confidence in structural and load-bearing applications.
• Open-mesh collar allows extra adhesive flow in hollow block applications - accommodates the unique demands of voids and cavities in hollow masonry, ensuring adequate fill and anchor performance.
• Epoxy screen tubes must be used with ET-3G formulation only - compatibility-specific design preserves the performance characteristics the system was engineered to achieve, preventing misapplication.

Why This Product

• Outperforms both steel and competing plastic screen tubes - the Opti-Mesh woven mesh insert is engineered to provide superior adhesive anchor performance while retaining the economical advantage of a plastic construction, giving buyers better value without sacrificing load capacity.
• Built-in safeguards reduce installation errors - the integral cap displays the required drill bit and rod diameter at a glance, and the flanges prevent the tube from sinking into over-drilled holes, so installers get it right the first time even in demanding field conditions.
• Optimized specifically for hollow block and brick anchoring - the open-mesh collar and formula-matched woven mesh work together to contain and distribute adhesive effectively in void-containing base materials where standard screens fall short.
• Made in the United States by Simpson Strong-Tie - backed by a trusted name in structural connection products, this screen tube is part of a complete adhesive anchoring system designed and supported by the same manufacturer.

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.
