Drop Forged C-Clamp, 0 - 4-1/4 in. Opening, 3-1/4 in. Throat Depth

Reliable enough for custom work, opens 0 to 4-1/4 in. with 6,200 lbs. of clamping force and a 3-1/4 in. throat depth. Drop forged steel construction provides the toughness and fatigue resistance required for daily use in production welding, metal fabrication, and industrial maintenance. Unlike cast frames that can crack under sudden impact, the forged grain structure absorbs shock loads and resists propagation of stress fractures over time. The acme thread spindle is hardened to maintain smooth, consistent tightening action even after thousands of clamping cycles. A self-adjusting swivel pad at the spindle tip distributes pressure evenly across workpiece surfaces, preventing point loading and surface marring. This clamp fills the role of a reliable, heavy-duty general-purpose C-clamp for shops that need forged quality without specialty features.
