The Simpson Opti-Mesh 13 in. Epoxy Adhesive Plastic Screen Tube for 3/4 in. Rod is engineered by Simpson to deliver consistent, reliable adhesive anchor performance in hollow or void-containing base materials such as hollow block and brick. Featuring a woven mesh insert, this formula-specific screen tube offers the cost advantage of a plastic construction while providing superior performance compared to steel screen tubes and competitive plastic screen tubes. Designed exclusively for use with the SET-3G epoxy adhesive formulation, it gives contractors and installers a purpose-built solution for demanding anchoring applications.

Key Features

• Integral cap centers the rod and displays drill bit and rod diameter - takes the guesswork out of installation by keeping the rod properly aligned and confirming correct sizing at a glance, reducing costly setup errors.
• Flanges prevent the screen tube from slipping into over-drilled holes - keeps the screen tube securely positioned even when hole depth varies, protecting anchor integrity and saving rework time.
• Formula-specific woven mesh design controls flow of adhesive out of the screen - ensures the right amount of SET-3G epoxy reaches the anchor zone for a consistent, fully developed bond every time.
• Open-mesh collar allows extra adhesive flow in hollow block applications - addresses the unique challenges of voids and hollow cavities, giving installers the adhesive distribution needed for reliable holding strength in these base materials.
• Designed exclusively for use with SET-3G epoxy adhesive - matching the screen tube to the correct formulation protects anchor performance and prevents compatibility issues that could compromise a finished installation.

Why This Product

• Plastic construction with performance that surpasses steel alternatives - the Opti-Mesh woven mesh insert gives buyers a more economical screen tube option without sacrificing the holding strength and adhesive control that demanding anchoring work requires.
• Purpose-built geometry for hollow and void-containing substrates - the combination of the open-mesh collar and formula-specific mesh design addresses the specific challenges of hollow block and brick anchoring, where standard installation methods often fall short.
• Built-in alignment and sizing cues simplify installation - the integral cap doubles as a centering guide and a quick reference for drill bit and rod diameter, reducing the chance of mismatched components and speeding up the anchoring process on the job site.
• Engineered by Simpson to work as a system - pairing this screen tube with SET-3G epoxy adhesive creates a matched, tested anchoring system designed to perform together, giving buyers confidence that every component is working as intended.
