This is the Klein 3227 — a 10-inch adjustable construction spud wrench with an extra-wide jaw that opens to 1-7/16 inches, which covers most structural bolts, mechanical couplings, and heavy hardware where a standard adjustable wrench runs out of capacity. The wider jaw is what makes this the construction spud, rather than a general-purpose wrench.
It’s the wrench for ironwork, structural steel, and heavy mechanical work where the fastener is oversized. The forged alloy-steel head holds tight tolerances under load, and the tether hole at the handle lets the tool be secured when working at height — a necessity on steel erection and tower work where a dropped tool is a real hazard.
Klein Tools has been making hand tools for electricians and tradespeople since 1857, headquartered in Lincolnshire, Illinois. The Journeyman and Standard pliers lines — along with many of Klein’s cushion-grip screwdrivers — are forged and finished in the United States, and clearly marked as such, so you know exactly what you’re buying.
