Insulating 4‑in‑1 lineman’s box wrench with four socket sizes and see‑through handle for electrical safety.
The Klein Tools Lineman’s Insulating 4‑in‑1 Box Wrench combines four common box socket sizes (½", 9⁄16", 5⁄8" and ¾") in one tool, ideal for pole hardware installation and removal. It meets the ASTM 1505‑10 1000 V insulating standard, and its transparent handle lets you visually confirm the metal ends are not electrically connected, enhancing safety on the job. Textured grooves improve grip, and a reverse ratcheting action makes it versatile and efficient.
