ABSTRACT:
An insert for use in a gripping assembly is disclosed. The insert includes a base member having a plurality of gripping teeth. The teeth are arranged in at least two substantially adjacent rows, where at least one row of teeth is offset or staggered longitudinally from an immediately adjacent row of teeth. When the teeth engage a cylindrical member, a resistance profile is created that is substantially continuous and does not oscillate over a length of the insert approaching 100% of the length of the entire insert.
