SOPI Pack Plastic Perforated Sleeves 12 × 50 mm, 5 pcs/bag, Injection Resin Sleeves for Hollow & Perforated Materials

SOPI Pack Plastic perforated sleeves 12 × 50 mm (5 pcs/bag) are plastic perforated sleeves designed for anchoring in hollow and perforated materials. The sleeves help keep injection resin in the drilled hole, reducing uncontrolled resin loss into voids and supporting a more secure anchor point. They are an essential system component when using injection resin in perforated brickwork and other hollow substrates.

Advantages and unique features

• 12 × 50 mm size – practical dimensions for typical anchoring holes in hollow substrates.
• Perforated sleeve design – supports proper resin distribution within the anchoring zone.
• Resin stabilisation in voids – helps reduce uncontrolled resin loss in hollow structures.
• System component for injection resins – helps achieve more consistent results in perforated masonry.
• Pack of 5 – convenient accessory supply for on-site work.

Properties and applications

• For hollow substrates: designed for anchoring in perforated bricks and hollow blocks.
• For injection resin: an accessory component supporting effective resin use in perforated masonry.
• Secure anchor point: helps create a more stable and reliable fixing point for anchors and threaded elements.
• Typical substrates (as described): perforated or hollow bricks, concrete, natural stone, drywall.
