Product Description\n\nThe plastic fischer injection anchor sleeve FIS H K is the system component for the use of fischer injection mortars in perforated brick masonry within through-type installations. To do so, the anchor sleeve is placed in the drill hole, and filled with injection mortar from the anchor sleeve base. When setting the rod anchor or the internal threaded anchor, the mortar is pressed through the lattice structure and then connects with the perforated brick by an interlock. This means that the load is directed into the building material. Non-bearing layers can also be bridged with the injection anchor sleeve.
