Functioning - The system can be used with any of the following injection mortars: FIS V, FIS VW HIGH SPEED, FIS VS LOW SPEED, FIS VT or FIS P Plus. FIS P can be used but does not have approvals. - The system is suitable for pre-positioned installation when combined with injection anchor sleeves and threaded rods FIS A or internal threaded anchors FIS E. - The anchor sleeve is placed in the drill hole, and filled with injection mortar from the anchor sleeve base. - Turning in the anchor causes the mortar to be pushed through the anchor sleeve's grating structure, so that it fits the base material perfectly. The load is borne by the interlock.
