KNARR offers two types of positioning wedges (51300). Depending on the length, either one (length 80 mm and 100 mm) or two (lengths 120 mm and 160 mm) extraction threads are incorporated. The positioning is either in the middle (type 1) or on the lateral edges (type 2). Both types are hardened to ~58 HRC and are available in heights of 30 mm, 45 mm, 60 mm and 80 mm. From lengths of 100 mm, the standard height of 100 mm is also offered.
