The fischer injection anchor sleeve FIS H K is the system component for professional and mortar-saving installation of the anchor rod FIS A or the internally threaded anchor FIS E in perforated brickwork. The fischer injection mortars FIS V, FIS VW HIGH SPEED, multifunctional mortar, assembly mortar and assembly mortar Green can be used for this purpose. The optimised grid structure reduces the consumption of the injection mortar. When setting the anchor rod and the internally threaded anchor, the mortar is pressed through the grid structure and bonds with the perforated brick in a positive fit. This transfers the load into the building material. The anchors are set using the pre-insertion method. The injection anchor sleeve can be used to bridge non-load-bearing layers. The approvals of the respective injection mortar must be observed.
