SOPI Pack Plastic Perforated Sleeves 20 × 85 mm, 5 pcs/bag, Injection Resin Sleeves for Hollow & Perforated Materials

SOPI Pack Plastic perforated sleeves 20 × 85 mm (5 pcs/bag) are plastic perforated sleeves designed for anchoring with injection resin in hollow and perforated substrates. The sleeves help keep resin within the anchoring zone, reduce resin loss into voids and support a stable anchor point. The 20 × 85 mm version is a good choice when a larger sleeve diameter is required for anchoring in hollow materials.

Advantages and unique features

• 20 × 85 mm size – larger sleeve diameter for hollow/perforated masonry.
• Perforated design – supports proper resin distribution within the anchoring zone.
• Reduced resin loss into voids – improved control in hollow blocks and perforated bricks.
• System component for injection resins – supports effective and repeatable anchoring in perforated brickwork.
• Pack of 5 – convenient accessory supply for on-site work.

Properties and applications

• For hollow/perforated substrates: designed for perforated bricks and hollow blocks, where resin may otherwise flow into voids.
• For injection resin: accessory component supporting effective resin use in perforated masonry.
• Stable anchor point: helps create a secure fixing point in substrates with voids.
• Typical substrates (as described): perforated/hollow bricks, concrete, natural stone, drywall.

Technical parameters

Storage recommendations

Store the sleeves in a clean, dry place in the original packaging to prevent dust and debris from blocking the perforations. Avoid loose storage in boxes contaminated with drilling dust. Before installation, check the sleeve condition and ensure the drilled hole is clean and appropriately sized for the sleeve to support controlled resin application.
