A 4-inch C-clamp from GreatNeck designed for woodworking, metalworking, welding fixtures, and general repair work. The C-shaped cast iron frame opens to 4" between the jaw faces, and the threaded steel forcing screw delivers controlled clamping pressure through a swiveling steel pad that grips both flat and angled work without spinning the piece.

The 4-inch jaw opening handles larger woodworking glue-ups, holds doubled 2x lumber for through-bolt work, and clamps fixtures during welding and brazing.

• Jaw opening (clamping capacity): 4"
• Cast iron C-frame - GreatNeck rates the frame as unbreakable under normal hand-tightening
• Forged steel forcing screw with nickel-plated threads for rust resistance and smooth operation
• Steel swivel pad pivots to grip angled surfaces without crushing or spinning the workpiece
• Sliding T-handle on the forcing screw for controlled hand pressure
• Backed by GreatNeck's lifetime warranty

Tip: Open the jaw past the workpiece thickness before positioning - it's faster to close the screw onto the work than to fight the screw open against the work surface.
