The Irwin Quick-Grip 4" Handi-Clamp opens wide enough for box, case, and cabinet assembly while still fitting comfortably in one hand. Squeeze the trigger to advance the moveable jaw with adjustable pressure, then press the quick-release lever to free your workpiece in an instant. The high-tech resin body stays light and rust-free, and the contoured non-slip pads protect finished surfaces.

• Jaw capacity: 4"
• Trigger advance and quick-release lever for true one-handed use
• Adjustable clamping pressure, lower hand force required
• Resin body with cushioned non-marring pads
• Ideal for box and case assembly, drawer glue-ups, edge-gluing thin panels, and holding jigs while a fastener is driven

Tip: A pair of 4" Handi-Clamps holds a small box square while the glue sets. For wider panels or door assembly, move up to a full-size Quick-Grip bar clamp.
