The Simpson Opti-Mesh 10 in. Acrylic Adhesive Plastic Screen Tube for 3/8 in. Rod is an engineered accessory from Simpson Strong-Tie, purpose-built to support reliable adhesive anchor installations in hollow block, brick, and other base materials that contain voids. The Opti-Mesh design pairs a formula-specific woven mesh insert with an open-mesh collar to control adhesive flow precisely where it is needed, delivering superior anchoring performance compared to steel screen tubes and competitive plastic screen tubes - all at the economical cost of a plastic construction. Compatible exclusively with the Simpson Strong-Tie AT-XP acrylic adhesive system, this screen tube is a critical component for contractors and installers who demand consistent, code-conscious results in hollow-base anchoring applications.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - keeps the rod properly positioned during installation and eliminates guesswork on job sites by putting sizing information directly on the tube.
• Flanges prevent the screen tube from slipping into over-drilled holes - ensures the tube stays in the correct position even when hole depth exceeds the target, reducing installation errors and wasted adhesive.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - regulates how adhesive disperses around the rod, producing a consistent and complete bond in void-containing base materials.
• Open-mesh collar allows extra adhesive flow in hollow block applications - accommodates the larger void spaces common in hollow block, giving adhesive the access it needs to form a strong anchor without over-pumping.
• Acrylic screen tube designed exclusively for use with AT-XP - screen tubes are formula-specific, so pairing this tube with the correct Simpson Strong-Tie AT-XP acrylic adhesive is essential for proper performance and compliance.

Why This Product

• Plastic construction with performance that exceeds steel alternatives - the Opti-Mesh woven mesh insert gives this plastic screen tube an edge over both steel screen tubes and competing plastic options, combining cost efficiency with elevated anchoring performance in hollow and void-containing substrates.
• Engineered for hollow block and brick anchoring - the open-mesh collar and controlled-flow mesh design work together to address the specific challenges of void-containing base materials, making this screen tube a purpose-built solution rather than a generic accessory.
• Built-in installation aids reduce on-site mistakes - the integral cap displays rod and drill bit sizing at a glance, and the flanges guard against over-drilled hole slippage, giving installers built-in checkpoints that protect both time and material investment.
• Part of the Simpson Strong-Tie adhesive dispensing system - designed to work within Simpson Strong-Tie's broader ecosystem of manual and pneumatic dispensing tools and accessories, this screen tube integrates seamlessly for a more efficient and consistent adhesive anchor workflow.

Frequently Asked Questions

Which adhesive must be used with the AWS3710P screen tube?

The AWS3710P is an acrylic screen tube specifically designed for use with the Simpson Strong-Tie AT-XP acrylic adhesive. Screen tubes are formula-specific, so this tube must only be used with AT-XP to ensure proper performance and code compliance.

Why are screen tubes necessary for 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 screen tube contains the adhesive around the rod within the void spaces, ensuring a proper bond is formed.

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

The Opti-Mesh screen tube features a formula-specific woven mesh insert that controls the flow of adhesive out of the screen, and an open-mesh collar that allows extra adhesive flow in hollow block applications. This design provides superior performance compared to both steel screen tubes and competitive plastic screen tubes.

What prevents the AWS3710P from slipping into an over-drilled hole?

The screen tube is equipped with flanges that prevent it from slipping into over-drilled holes, ensuring it stays correctly positioned during the adhesive anchoring process. The integral cap also assists by centering the rod and displaying the correct drill bit and rod diameter.
