The fischer injection anchor sleeves are the system components for using the fischer injection mortar in perforated brick. The anchor sleeves are placed in the drill hole and filled with injection mortar from the base of the anchor sleeves. When the threaded rod or internal threaded anchor is installed, the mortar is pressed through the grating structure and creates a form fit with the perforated brick. This directs the load into the building material. You can also use the injection anchor sleeve to bridge non-load-bearing layers.
