The Simpson Opti-Mesh 8 in. Epoxy Adhesive Plastic Screen Tube for 3/4 in. Rod is engineered by Simpson to deliver reliable adhesive anchoring performance in base materials that are hollow or contain voids, such as hollow block and brick. Featuring a woven mesh insert, this plastic screen tube provides the economical advantages of a plastic construction while delivering superior performance compared to steel screen tubes and competitive plastic screen tubes - making it a dependable choice for 3/4 in. rod installations requiring consistent, high-load adhesive coverage.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - takes the guesswork out of installation by confirming correct setup at a glance, reducing the risk of misaligned or undersized hole preparation
• Flanges prevent the screen tube from slipping into over-drilled holes - keeps the tube properly positioned during installation even when hole depth exceeds the target, protecting anchor integrity
• Formula-specific woven mesh design controls flow of adhesive out of the screen - ensures adhesive is distributed precisely where it is needed, maximizing bond consistency across the full rod surface
• Uniform coverage of adhesive on the rod results in higher loads than for rods installed with standard screen - translates directly to stronger, more reliable anchors in structural and construction applications
• Open-mesh collar allows extra adhesive flow in hollow block applications - accommodates the unique voids found in hollow block and brick substrates, ensuring adequate fill in challenging base materials
• Designed exclusively for use with the ET-3G epoxy adhesive formulation - compatibility is built into the design, so the mesh performance is optimized for the specific flow characteristics of epoxy adhesive, preventing misuse with incompatible formulations

Why This Product

• Outperforms both steel and competing plastic screen tubes - the Opti-Mesh woven mesh insert delivers superior adhesive control and uniform rod coverage, producing higher anchor loads without the cost premium of steel alternatives
• Engineered for hollow and void-containing base materials - the open-mesh collar design specifically addresses the challenges of hollow block and brick anchoring, where standard screen tubes often fail to provide adequate adhesive distribution
• Built-in installation safeguards reduce costly errors - the integral cap with drill bit and rod diameter display, combined with slip-preventing flanges, gives installers immediate visual confirmation of correct setup and keeps the tube securely in place throughout the anchoring process
• Formula-matched design protects anchor performance - pairing this epoxy screen tube with the ET-3G formulation ensures the mesh flow characteristics are precisely calibrated for that adhesive, maintaining the load performance the system is rated to deliver

Frequently Asked Questions

What adhesive formulation is the EWS758P screen tube compatible with?

The EWS758P Opti-Mesh epoxy screen tube is specifically designed for use with the Simpson Strong-Tie ET-3G epoxy adhesive formulation. Screen tubes are designed for a specific adhesive type, so epoxy screen tubes must be used with the ET-3G formulation only.

What rod diameter and hole size does this screen tube accommodate?

This screen tube is designed for a 3/4 in. rod diameter and requires a 1 in. drilled hole size. The tube itself measures 8 in. in length.

Why does the Opti-Mesh screen tube outperform standard screen tubes?

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 design also outperforms both steel screen tubes and competitive plastic screen tubes.

What prevents the EWS758P screen tube from slipping into an over-drilled hole?

The EWS758P features flanges that prevent the screen tube from slipping into over-drilled holes, ensuring proper positioning during installation. Additionally, the integral cap centers the rod and displays the correct drill bit and rod diameter for easy reference.
