Fischer FIS H 20 × 130 K mesh sleeves, plastic with hook, for hollow masonry, 20 mm drill, pack of 20

The fischer FIS H 20 × 130 K mesh sleeve is a plastic insert for injection anchoring in hollow masonry. The mesh structure optimises resin flow and shaping, reduces mortar consumption, and provides reliable mechanical interlock within the cavity walls.

Benefits and unique features

• Mesh design lowers mortar consumption while maintaining high load capacity.
• Centering wings stabilise the rod and anchor for faster installation.
• Hooked version prevents the sleeve from falling out during overhead work.
• Accepts multiple rod diameters – simpler site logistics.
• ETA assessment – system-approved solution.

Properties and applications

• Use: economical fixing of threaded rods or internal-thread anchors in hollow masonry (ceramic blocks, lightweight concrete, sand-lime, etc.).
• Injection mortars: FIS V, FIS VL, FIS V High Speed, FIS VS Low Speed, FIS Green, FIS P, FIS P Plus – as per their documentation.
• How it works: mortar pressed through the mesh bonds non-loadbearing and loadbearing layers to form a shaped, repeatable embedment.

Technical parameters

Storage recommendations

Store in a dry, cool place in the original packaging. Protect from UV and contamination that could hinder sleeve seating or mortar flow. Avoid long-term mechanical stress on the mesh during storage.
