SOPI Pack Plastic Perforated Sleeves 16 × 85 mm, 5 pcs/bag, Injection Resin Sleeves for Hollow & Perforated Materials

SOPI Pack Plastic perforated sleeves 16 × 85 mm (5 pcs/bag) are plastic perforated sleeves designed for anchoring with injection resin in hollow and perforated substrates. The sleeves stabilise resin in the drilled hole and reduce resin loss into voids, helping create a more secure and predictable anchor point. The 16 × 85 mm version is a good choice when a larger diameter and a longer anchoring zone are required in hollow materials.

Advantages and unique features

• 16 × 85 mm size – larger diameter and longer sleeve for hollow/perforated substrates.
• Perforated design – supports even resin distribution within the anchoring zone.
• Reduced resin loss into voids – improved control in perforated masonry.
• System component for injection resins – supports effective anchoring in perforated brickwork and hollow blocks.
• 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.
• Secure anchor point: helps create a stable 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. Before installation, check the sleeve condition and ensure the drilled hole is clean and appropriately sized for the sleeve.
