540A Series C-Clamp 0 - 4 in. Opening Capacity

With a 4 in. jaw opening and 2,150 lbs. of holding power, this clamp features a 2-1/16 in. throat depth. Constructed from ductile iron, this carriage-style clamp delivers reliable holding power for woodworking, light fabrication, and assembly operations. The acme thread spindle engages smoothly at every point along the opening range, applying even pressure without the stick-slip common in lesser designs. A swivel pad at the spindle tip automatically conforms to workpiece angles, protecting finished surfaces while maintaining a secure grip. The 540A carriage frame profile keeps overall weight manageable without sacrificing the stiffness needed to resist deflection under full load. Whether securing panel glue-ups or holding stock for drilling, this clamp performs consistently across repeated clamping cycles.
