The Simpson Opti-Mesh 6 in. Epoxy Adhesive Plastic Screen Tube for 3/8 in. Rod is engineered by Simpson Strong-Tie to deliver reliable, controlled adhesive dispensing in hollow or void-containing base materials such as hollow block and brick. This gray plastic screen tube features a formula-specific woven mesh insert that provides the economical advantage of a plastic screen tube while delivering superior performance to steel screen tubes and competitive plastic screen tubes - making it a dependable choice for adhesive anchor installations where consistent adhesive flow and proper rod positioning are critical. Designed exclusively for use with the SET-3G epoxy adhesive formulation, this screen tube is a purpose-built accessory that helps ensure correct, efficient installation every time.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - takes the guesswork out of installation by keeping the rod properly aligned and confirming the correct hole size at a glance, reducing the risk of costly errors.
• Flanges prevent the screen tube from slipping into over-drilled holes - maintains proper positioning during installation even when the drilled hole is deeper than intended, protecting anchor performance.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - ensures the SET-3G epoxy disperses evenly around the rod for a consistent, fully bonded anchor in solid base materials.
• Open-mesh collar allows extra adhesive flow in hollow block applications - promotes adequate adhesive distribution in voids and cavities, supporting reliable load transfer in hollow block and brick substrates.
• Designed exclusively for use with SET-3G epoxy adhesive - the formula-specific construction ensures compatibility and proper adhesive flow; using the correct screen tube with the correct adhesive is essential to anchor performance and safety.

Why This Product

• Superior performance at a practical price point - the Opti-Mesh woven mesh insert delivers better adhesive flow control than steel screen tubes and competitive plastic alternatives, giving contractors a high-performing option without the cost premium of steel.
• Built-in installation safeguards reduce errors on the job - the integral cap displays the required drill bit and rod diameter directly on the tube, and the flanges prevent the screen from disappearing into over-drilled holes, helping crews work accurately and efficiently.
• Purpose-designed for hollow and void-containing base materials - the open-mesh collar and controlled-flow woven mesh work together to handle the demands of hollow block and brick anchoring, where uncontrolled adhesive flow would compromise holding strength.
• Part of a complete Simpson Strong-Tie adhesive anchoring system - engineered as a matched accessory for the SET-3G epoxy formulation, this screen tube integrates seamlessly with Simpson Strong-Tie dispensing tools and accessories for a consistent, system-level installation experience.

Frequently Asked Questions

What adhesive formulation must be used with this screen tube?

This Opti-Mesh screen tube is designed specifically for use with the SET-3G epoxy adhesive formulation. Epoxy screen tubes must not be substituted with screen tubes designed for other adhesive types, as each screen tube is formula-specific to ensure proper adhesive flow and anchor performance.

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

This screen tube is designed for a 3/8 in. rod diameter and requires a 9/16 in. hole size. The integral cap conveniently displays both the required drill bit size and rod diameter to help prevent installation errors.

Why use a plastic screen tube instead of a steel screen tube?

The Simpson Strong-Tie Opti-Mesh screen tube with woven mesh insert provides the economical advantage of a plastic screen tube while delivering superior performance to both steel screen tubes and competitive plastic screen tubes, making it a cost-effective yet high-performing choice for adhesive anchor applications.

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

The screen tube is equipped with flanges that prevent it from slipping into over-drilled holes, helping to maintain proper positioning during adhesive dispensing. Additionally, the open-mesh collar allows extra adhesive flow specifically in hollow block applications where voids are present.
