The Simpson Opti-Mesh 6 in. Epoxy Adhesive Plastic Screen Tube for 5/8 in. Rod is engineered by Simpson Strong-Tie exclusively for use with the SET-3G epoxy adhesive formulation, making it an essential component for anchoring applications in base materials that are hollow or contain voids, such as hollow block and brick. Featuring a formula-specific woven mesh insert, this gray plastic screen tube delivers the cost-effectiveness of a plastic design while providing superior performance compared to steel screen tubes and competitive plastic screen tubes - giving contractors and installers a reliable, application-matched solution for adhesive anchor installations.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - eliminates guesswork on the job site by keeping the rod properly aligned and giving installers an at-a-glance reference for the correct hole size during drilling and placement.
• Flanges prevent the screen tube from slipping into over-drilled holes - keeps the tube correctly positioned throughout the adhesive dispensing process, reducing the risk of installation errors and wasted material.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - ensures consistent, uniform adhesive distribution optimized for the SET-3G formulation, supporting a secure and properly cured anchor bond.
• Open-mesh collar allows extra adhesive flow in hollow block applications - promotes thorough adhesive coverage in voids and hollow cavities, where proper fill is critical to anchor strength and performance.
• Designed exclusively for use with SET-3G epoxy adhesive - the formula-specific construction means this screen tube works in precise coordination with SET-3G chemistry, helping installers maintain compatibility and avoid performance-compromising mismatches.

Why This Product

• Purpose-built for hollow substrate anchoring - the Opti-Mesh design addresses the specific challenges of installing adhesive anchors in hollow block, brick, and void-containing base materials, where a standard screen tube would fail to control adhesive flow effectively.
• Outperforms steel and competing plastic screen tubes - Simpson Strong-Tie's woven mesh insert technology delivers superior adhesive containment and flow control, giving installers more confidence in anchor performance without paying a premium for steel alternatives.
• Built-in installation safeguards reduce costly errors - the integral cap with drill bit and rod diameter markings, combined with slip-preventing flanges, streamlines the installation process and helps prevent common field mistakes before they happen.
• Made in the United States by a trusted anchor systems manufacturer - backed by Simpson Strong-Tie's engineering expertise, this screen tube is part of a coordinated adhesive anchoring system that includes matching dispensing tools and accessories designed to work together efficiently.

Frequently Asked Questions

Which adhesive formulation must be used with this screen tube?

This screen tube is designed exclusively for use with the SET-3G epoxy adhesive formulation. Screen tubes are formula-specific, and epoxy screen tubes must only be used with SET-3G. Using an incompatible adhesive may compromise anchor performance.

What hole size is required when installing this screen tube?

This screen tube requires a drilled hole size of 7/8 in. to accommodate the 5/8 in. rod diameter. The integral cap on the tube displays both the required drill bit size and rod diameter for easy reference during installation.

Why are screen tubes necessary for hollow block and brick applications?

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 design includes an open-mesh collar that allows extra adhesive flow in hollow block applications, ensuring proper adhesive distribution and a secure anchor.

How does the flange design benefit installation?

The flanges on this screen tube are specifically designed to prevent the tube from slipping into over-drilled holes, keeping it properly positioned during adhesive dispensing and rod insertion for a consistent and reliable anchor installation.
