The Simpson Opti-Mesh 6 in. Epoxy Adhesive Plastic Screen Tube for 1/2 in. Rod is an engineered plastic screen tube built specifically for use with the SET-3G epoxy adhesive formulation. Designed by Simpson Strong-Tie to improve the efficiency and reliability of adhesive anchor installations, this screen tube is essential when working in base materials that are hollow or contain voids, such as hollow block and brick. Its formula-specific woven mesh insert controls adhesive flow precisely, giving installers the economical benefits of a plastic screen tube while delivering superior performance compared to steel screen tubes and competing plastic screen tubes.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - eliminates guesswork on the job site, helping ensure the correct rod and hole size are used every time for a properly seated anchor.
• Flanges prevent the screen tube from slipping into over-drilled holes - keeps the tube positioned correctly even when the drilled hole is slightly deeper than intended, protecting installation integrity.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - ensures optimal adhesive distribution around the anchor rod, which is critical to achieving full load-rated performance.
• Open-mesh collar allows extra adhesive flow in hollow block applications - accommodates the unique demands of hollow substrates by enabling sufficient adhesive to reach and fill the void areas around the anchor.
• Engineered exclusively for the SET-3G epoxy formulation - the matched design between screen tube and adhesive type ensures chemical compatibility and consistent anchor performance; using a mismatched screen tube can compromise results.

Why This Product

• Purpose-built for hollow base materials - screen tubes are vital when anchoring into hollow block, brick, or any base material containing voids, and this Opti-Mesh tube's open-mesh collar and woven mesh design work together to deliver reliable adhesive distribution where a standard installation method would fail.
• Outperforms steel and competing plastic screen tubes - the Opti-Mesh woven mesh insert provides superior adhesive flow control compared to both steel screen tubes and other plastic screen tube options, giving buyers a higher-performing solution at a more economical price point.
• Reduces installation errors through built-in guidance features - the integral cap communicates the required drill bit and rod diameter directly on the accessory itself, and the flanges guard against mis-seating in over-drilled holes, making correct installation more straightforward for any crew.
• Backed by Simpson Strong-Tie's adhesive anchor system - as part of a complete adhesive dispensing and anchoring system, this screen tube is designed to work seamlessly with SET-3G epoxy and Simpson Strong-Tie dispensing tools, supporting a consistent, efficient workflow from drilling to final cure.

Frequently Asked Questions

Which adhesive formulation must be used with this screen tube?

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

What rod diameter and hole size is this screen tube compatible with?

This screen tube is designed for a 1/2 in. rod diameter and requires a 3/4 in. drilled hole size.

Why are screen tubes 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's woven mesh design controls the flow of adhesive while the open-mesh collar allows extra adhesive flow specifically in hollow block applications, ensuring proper adhesive distribution and anchor performance.

How does the Opti-Mesh design prevent installation errors?

The integral cap on the Opti-Mesh screen tube centers the rod and displays the required drill bit and rod diameter, helping ensure correct installation. Additionally, the flanges on the tube prevent it from slipping into over-drilled holes, adding a safeguard against common installation issues.
