Functioning - The FHB II-A L is a bonded anchor with torque-controlled expansion for pre-positioned and push-through installation. - When using FHB II-A L in push-through installation, the annular gap is to be filled with the injection mortar FIS HB. - The anchor rod can be set either with injection mortar FIS HB or with the capsule FHB II-P / FHB II-PF HIGH SPEED, and is fully bonded in the drill hole. - When tightening the hexagon nut, the anchor rod cones are pulled into the mortar shell, which expands against the drill hole wall. - The styrene-free vinyl ester mortar fully seals the drill hole. - When using the resin capsule, set the anchor rod through rotating and hitting motions with a hammer drill. Use the RA-SDS setting tool, Art.-No. 62420.
