The Simpson Opti-Mesh 13 in. Epoxy Adhesive Plastic Screen Tube for 3/4 in. Rod is engineered by Simpson to maximize the performance of adhesive anchors in hollow or void-containing base materials such as hollow block and brick. The Opti-Mesh design pairs the cost efficiency of a plastic screen tube with a formula-specific woven mesh insert that delivers superior performance compared to steel screen tubes and competitive plastic screen tubes - making it a reliable choice for professionals who need consistent, high-load anchor results with ET-3G epoxy adhesive.

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 correct tooling at a glance
• Flanges prevent the screen tube from slipping into over-drilled holes - protects against a common installation error, helping ensure the tube stays in the correct position for a secure anchor
• Formula-specific woven mesh design controls flow of adhesive out of the screen - regulates adhesive distribution precisely, so the right amount reaches the right areas every time
• Uniform coverage of adhesive on the rod results in higher loads than for rods installed with standard screen - directly translates to stronger, more dependable anchors in structural and fastening applications
• Open-mesh collar allows extra adhesive flow in hollow block applications - accommodates the unique void patterns of hollow block, ensuring complete coverage where standard screens fall short
• Designed exclusively for use with ET-3G epoxy adhesive formulation - compatibility is built into the product design, reducing the risk of mismatched materials and installation failures

Why This Product

• Outperforms standard and steel screen tubes without the added cost - the Opti-Mesh woven mesh insert provides superior adhesive control and load performance compared to both steel screen tubes and competing plastic options, giving buyers a high-performance solution at a practical price point
• Purpose-built for hollow base materials - the open-mesh collar and formula-specific mesh design work together to handle the challenges of hollow block, brick, and other void-containing substrates where adhesive distribution is most critical
• Reduces installation errors through smart design details - the integral cap with rod and drill bit markings, combined with flanges that prevent over-insertion, helps crews achieve consistent, repeatable results on every anchor installation
• Made in the United States by a trusted name in structural fastening - Simpson engineering and domestic production back every screen tube, giving contractors confidence in quality and dimensional accuracy for 3/4 in. rod anchoring applications

Frequently Asked Questions

Which adhesive formulation is this screen tube compatible with?

This Opti-Mesh screen tube is designed specifically for use with the ET-3G epoxy adhesive formulation. Epoxy screen tubes must be used with the ET-3G formulation. Screen tubes are designed for a specific adhesive type, so always verify compatibility before installation.

What rod diameter and hole size is the EWS7513P designed for?

The EWS7513P is designed for a 3/4 in. rod diameter and requires a 1 in. hole size, with an overall length of 13 in.

How does the Opti-Mesh screen tube prevent installation errors in over-drilled holes?

The screen tube features flanges that prevent it from slipping into over-drilled holes, and an integral cap that centers the rod while displaying the correct drill bit and rod diameter - helping to ensure proper placement and consistent results.

Why use the Opti-Mesh screen tube instead of a standard screen tube?

The formula-specific woven mesh design controls the flow of adhesive out of the screen, resulting in uniform coverage of adhesive on the rod. This uniform coverage produces higher loads than rods installed with standard screen tubes, and the open-mesh collar allows extra adhesive flow in hollow block applications for superior anchoring performance.
