Irwin Quick-Grip 4 in. X 2-7/8 in. D Adjustable C-Clamp

The Irwin Quick-Grip 100 Series 4-inch C-Clamp uses a double-rolled thread for faster clamping and increased durability and features a larger swivel pad to reduce marring on work surfaces and increase stability. A larger handle gives greater clamping pressure with less effort and reduced hand fatigue.
