540A Series Carriage C-Clamp Kit

Opening up to 8 in. with 3-1/4 in. throat depth, the largest clamp in this set generates 2,750 lbs. of clamping force. Each 540A clamp features a ductile iron frame that absorbs impact without cracking, paired with a precision acme thread spindle for smooth tightening under load. The carriage-style jaw design is lighter than standard C-clamp frames while maintaining rigidity across the full opening range. Swivel pads on every clamp self-adjust to angled or irregular surfaces, distributing force evenly and preventing workpiece damage. This kit provides the range of sizes most commonly needed in a single purchase, reducing setup time when switching between stock thicknesses.
