Klein Tools' Tool Holder Tension Straps were designed to secure Klein's Bull Pin Holder (Cat. No. 5817) and Spud Wrench Holder (Cat. No. 5860) to a toolbelt, not included. The Heat-resistant aramid fiber straps add resistance to the tool holder to help reduce sliding on most nylon, leather and canvas belts. Straps in this 4-Pack can be easily loosen and readjusted when needed.
