The CrossConnector 2.0 T-Set makes it easy to attach the InsertionRail 2.0 to any K2 mounting rail. The screws are located outside the mounted InsertionRail, which offers the advantage that the rail, including the CrossConnector, can still be moved vertically on the rail after mounting. All accessories required for installation are included in this set. Material: Aluminium EN-AW 6060 T66; stainless steel 1.4301; A2-70, TPC.
