The Simpson Opti-Mesh 10 in. Epoxy Adhesive Plastic Screen Tube for 1/2 in. Rod is engineered by Simpson to maximize the performance of adhesive anchors in base materials that are hollow or contain voids, such as hollow block and brick. Featuring a formula-specific woven mesh insert, this screen tube delivers the economical advantage of plastic construction while providing superior performance compared to steel screen tubes and competitive plastic screen tubes. Designed exclusively for use with the ET-3G epoxy adhesive formulation, it ensures uniform adhesive coverage on the rod for higher load capacity and dependable anchoring results in demanding structural applications.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - takes the guesswork out of setup, helping installers quickly confirm correct sizing before dispensing adhesive.
• Flanges prevent the screen tube from slipping into over-drilled holes - keeps the tube properly positioned throughout the installation process, reducing the risk of misalignment and wasted adhesive.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - ensures adhesive is distributed at the right rate, preventing voids and inconsistent coverage that can weaken an anchor.
• Uniform coverage of adhesive on the rod results in higher loads than for rods installed with standard screen - delivers measurably stronger anchoring performance, giving contractors and engineers greater confidence in load-bearing applications.
• Open-mesh collar allows extra adhesive flow in hollow block applications - accommodates the unique demands of voids and cavities in hollow block and brick, helping to ensure full encapsulation where it matters most.
• Epoxy screen tubes must be used with ET-3G formulation - matching the screen to the correct adhesive type is critical to anchor performance; this tube is purpose-built for ET-3G to maintain system integrity.

Why This Product

• Plastic construction with performance that exceeds steel alternatives - the Opti-Mesh woven mesh insert gives this plastic screen tube a measurable performance edge over both steel screen tubes and competing plastic options, so buyers get superior anchoring results without paying a premium for steel.
• Purpose-built for hollow base materials - the open-mesh collar and woven mesh design work together to handle the challenges of hollow block, brick, and void-containing substrates, making this screen tube a reliable choice for masonry and concrete anchor installations.
• Precision design features reduce installation errors - the integral cap with diameter markings and flanges that resist slipping into over-drilled holes make this screen tube notably easier to install correctly, helping crews work faster and with fewer costly mistakes on the job.
• System-matched adhesive anchor component from Simpson - as part of the Simpson adhesive anchor system, this screen tube is engineered to work specifically with ET-3G epoxy adhesive, ensuring every element of the anchor assembly is optimized to deliver consistent, high-load results.

Frequently Asked Questions

What adhesive formulation must be used with the EWS5010P screen tube?

The EWS5010P 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 adhesive can compromise anchor performance.

What is the purpose of the flanges on this screen tube?

The flanges on the EWS5010P are designed to prevent the screen tube from slipping into over-drilled holes, helping to ensure the tube stays properly positioned during adhesive dispensing and rod installation.

Why does the Opti-Mesh screen tube provide higher load performance than a standard screen?

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 is what produces higher loads compared to rods installed with a standard screen tube.

Is the EWS5010P suitable for use in hollow block or brick applications?

Yes. The EWS5010P is specifically designed for use in base materials that are hollow or contain voids, such as hollow block and brick. Its open-mesh collar allows extra adhesive flow in hollow block applications to help ensure proper anchoring.
