Simpson Strong-Tie Opti-Mesh 6 in. Epoxy Adhesive Plastic Screen Tube for 5/8 in. Rod (Model EWS626P) is engineered by Simpson Strong-Tie to work specifically with the ET-3G epoxy adhesive formulation, making it an essential accessory for anchoring 5/8 in. threaded rod in hollow or voided base materials such as hollow block and brick. The Opti-Mesh woven mesh insert design delivers superior adhesive flow control and uniform rod coverage, resulting in higher load performance compared to standard steel screen tubes and competitive plastic screen tubes.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter
• Flanges prevent the screen tube from slipping into over-drilled holes
• Formula-specific woven mesh design controls flow of adhesive out of the screen
• Uniform coverage of adhesive on the rod results in higher loads than for rods installed with standard screen
• Open-mesh collar allows extra adhesive flow in hollow block applications
• Provides the economical advantage of a plastic screen tube while delivering performance superior to steel screen tubes and competitive plastic screen tubes
• Caution: Screen tubes are designed for a specific adhesive type; epoxy screen tubes must be used with ET-3G formulation

Frequently Asked Questions

What adhesive formulation must be used with the EWS626P screen tube?

The EWS626P is an epoxy screen tube and must be used exclusively with the ET-3G epoxy adhesive formulation. Screen tubes are designed for a specific adhesive type, and using an incompatible formulation can compromise anchor performance.

What rod diameter and hole size is the EWS626P designed for?

The EWS626P is designed for a 5/8 in. rod diameter and requires a drilled hole size of 7/8 in. The integral cap displays both the drill bit and rod diameter for easy reference during installation.

Why is a screen tube necessary in hollow block or 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 open-mesh collar allows extra adhesive flow in hollow block applications, ensuring the adhesive is properly contained and distributed for a reliable anchor.

How does the Opti-Mesh design improve performance over standard screen tubes?

The formula-specific woven mesh design controls the flow of adhesive out of the screen, delivering uniform coverage of adhesive on the rod. This uniform coverage results in higher loads than those achieved with rods installed using a standard screen, and it outperforms both steel screen tubes and competitive plastic screen tubes.
