The Simpson Opti-Mesh 10 in. Epoxy Adhesive Plastic Screen Tube for 5/8 in. Rod is purpose-built by Simpson Strong-Tie to deliver reliable adhesive anchoring in hollow base materials such as hollow block and brick where voids would otherwise prevent a standard installation. Its formula-specific woven mesh insert sets it apart from both steel screen tubes and competitive plastic screen tubes, combining the cost efficiency of a plastic tube with superior anchoring performance. Designed exclusively for use with the ET-3G epoxy adhesive formulation, this screen tube gives contractors and installers a precise, high-load anchoring solution for 5/8 in. threaded rod applications.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - eliminates guesswork during setup, helping installers quickly confirm correct bit and rod sizing before driving the anchor.
• Flanges prevent the screen tube from slipping into over-drilled holes - keeps the tube properly positioned even when the hole depth is slightly greater than intended, protecting installation integrity.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - ensures the ET-3G epoxy distributes at the right rate, preventing waste and promoting a consistent bond throughout the anchor zone.
• Uniform coverage of adhesive on the rod results in higher loads than for rods installed with standard screen - delivers stronger, more dependable anchor capacity compared to installations using conventional screen tubes.
• Open-mesh collar allows extra adhesive flow in hollow block applications - accommodates the additional adhesive volume needed to fill voids in hollow block, ensuring full encapsulation of the rod in challenging base materials.
• Epoxy screen tubes must be used with the ET-3G formulation only - matching the tube to the correct adhesive type is critical to performance; this pairing keeps installations code-compliant and structurally sound.

Why This Product

• Outperforms standard and competing screen tubes - the Opti-Mesh woven mesh insert produces uniform adhesive coverage on the rod that yields higher anchor loads than rods installed with standard screen tubes, including competing plastic options, giving buyers more structural confidence per installation.
• Engineered specifically for hollow-base anchoring - the open-mesh collar and formula-specific mesh design work together to manage adhesive flow in void-containing materials like hollow block and brick, where reliable epoxy anchoring would otherwise be difficult to achieve.
• Built-in alignment and sizing guidance reduces installation errors - the integral cap centers the rod automatically and clearly displays the required drill bit and rod diameter, keeping installations accurate without additional measuring tools or guesswork on the job site.
• Plastic construction with security features that prevent tube loss - the flanged design stops the tube from falling into over-drilled holes, combining the economical advantage of a plastic tube with a practical safeguard that keeps the installation on track.
