The Simpson Opti-Mesh 6 in. Acrylic Adhesive Plastic Screen Tube for 1/2 in. Rod is purpose-built to support reliable adhesive anchor installations in hollow or void-containing base materials such as hollow block and brick. Engineered by Simpson Strong-Tie, this plastic mesh screen tube pairs exclusively with AT-XP acrylic adhesive, ensuring the formula-specific woven mesh controls adhesive flow precisely and delivers performance that surpasses steel screen tubes and competitive plastic screen tubes. Whether anchoring into hollow block or navigating challenging void-heavy substrates, this screen tube is a critical component for consistent, high-quality adhesive anchor results.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - keeps the threaded rod properly aligned during installation and puts required sizing information right at the workface, reducing errors on the job.
• Flanges prevent the screen tube from slipping into over-drilled holes - maintains correct tube positioning even when holes are drilled slightly long, so adhesive is dispensed where it needs to be every time.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - optimizes adhesive distribution throughout the anchor hole for a consistent, reliable bond in hollow and void-containing base materials.
• Open-mesh collar allows extra adhesive flow in hollow block applications - ensures adequate coverage around the rod in open cavities where standard flow would be insufficient, supporting full anchor engagement.
• Acrylic screen tubes must be used with AT-XP - matching the screen tube to the correct adhesive type is essential; this tube is specifically designed and validated for AT-XP acrylic adhesive to protect anchor integrity.

Why This Product

• Optimized for AT-XP acrylic adhesive anchor systems - the formula-specific mesh design works in direct coordination with AT-XP chemistry, meaning buyers get a screen tube engineered to the adhesive rather than a generic accessory that compromises performance.
• Delivers plastic economy with superior performance - the Opti-Mesh woven mesh insert gives contractors the cost advantage of a plastic screen tube while outperforming both steel screen tubes and competing plastic options, making it a practical upgrade for hollow base material applications.
• Built-in installation safeguards reduce costly mistakes - the integral cap with printed sizing reference and the anti-slip flanges work together to keep installations accurate and on-spec, even in fast-paced field conditions.
• Versatile performance in void-containing substrates - the open-mesh collar design specifically addresses the challenge of adhesive coverage in hollow block and brick, making this screen tube the right choice for anchoring projects where base material voids would otherwise limit bond quality.

Frequently Asked Questions

What adhesive must be used with the AWS506P screen tube?

The AWS506P is an acrylic screen tube and must be used exclusively with AT-XP acrylic adhesive. Screen tubes are designed for a specific adhesive type, and using a mismatched adhesive can compromise anchor performance.

What base materials is this screen tube designed for?

This screen tube is designed for use in base materials that are hollow or contain voids, such as hollow block and brick. The open-mesh collar specifically allows extra adhesive flow in hollow block applications to ensure proper coverage and bond strength.

What drill bit hole size is required for the AWS506P?

The AWS506P requires a 3/4 in. diameter hole to accommodate the screen tube, which is designed for a 1/2 in. diameter rod. The integral cap displays both the required drill bit and rod diameter for easy reference during installation.

How do the flanges on the AWS506P improve installation?

The flanges on the AWS506P are designed to prevent the screen tube from slipping into over-drilled holes, ensuring the tube remains properly positioned during adhesive dispensing and rod installation for consistent, reliable anchor performance.
