CLGR® C Clamp Cast Steel, also known as G Clamp, Cast Steel C-Clamp, C-clamp Cast steel G-clamp.
The C Clamp is built with a double rolled thread that delivers greater clamping speed, helping you complete setups faster. The large handle provides increased clamping pressure with less effort, reducing hand fatigue during extended use. Thanks to its low-resistance screw threading, binding and sticking are minimized for smooth, reliable operation.
The large swivel pad reduces marring on the work surface while improving overall stability. It automatically adjusts to fit a variety of workpiece shapes and sizes, so you don’t need to reposition the clamp constantly. The screw's low-resistance finish ensures smooth clamping every time.
Designed with a durable steel C-shaped frame, these clamps are ideal for holding wood and metal tight during gluing or welding projects. They are available in a wide range of sizes, throat depths, and capacities to meet your shop's needs. Whether you are doing metalworking or woodworking, the CLGR® C Clamp provides a secure, dependable hold.
