IRWIN Quick-Grip 12-Inch One-Handed Bar Clamp
IRWIN's classic one-handed bar clamp in the 12-inch medium-duty size. Squeeze the trigger to close it with one hand while the other holds the work, and flip the jaws around to spread instead of clamp.
Quick verdict
Yes, if you need to hold work with one hand while gluing, drilling or cutting with the other. The IRWIN Quick-Grip 12-inch medium-duty clamp closes with a trigger squeeze, and its jaws reverse so it can spread instead of clamp. It's sold singly here and isn't meant for wide tabletop glue-ups or maximum clamping pressure.
- Best for:
- One-handed DIY clamping.
- Watch out:
- Medium duty; buy two.

Our Take
The Quick-Grip is the clamp most DIYers buy first, because it works with one hand. You hold the pieces with one hand and squeeze the pistol grip to close the jaws with the other; a trigger releases it instantly. The listing rates this medium-duty 12-inch clamp at 300 pounds of sustained clamping force with a 3-3/16-inch throat, and a quick-change button turns it into a spreader. The swivel jaws have removable non-marring pads to protect wood. It suits glue-ups of shelves, drawers and small frames. It won't replace heavy-duty bar or pipe clamps for big panel glue-ups, and most projects need at least two. We haven't tested it ourselves.

Why PriceDropIQ Selected It
It solves the classic DIY problem of needing three hands: hold the parts with one hand and close the clamp with the other. The 12-inch size covers most shelf, drawer and frame glue-ups. Buy at least two, and step up to the heavy-duty version if you need serious pressure.
