The DONGCHENG HD071012 12 Inch (300 mm) Heavy-Duty G-Clamp is made for carpenters, welders, fabricators, mechanics, and industrial users who need a firm, reliable hold on very large work while cutting, gluing, drilling, or welding. The screw spindle opens to 300 mm and tightens with a sliding T-handle, so you can set the pressure by hand and keep both hands free for the job. The wide opening handles thicker stock, beams, and bigger assemblies than any other clamp in the range, from the 2 inch up to the 8 inch model.

Safety Note:
Do not exceed the clamp's rated load, and do not use a pipe or tool to extend the handle for extra tightening, as this can damage the clamp or cause injury. Do not use it as a hammer or for lifting. Check the frame and screw for cracks or wear before use. Wear eye protection when clamping parts for cutting, grinding, or welding. This is a heavy tool, so take care when lifting and handling it.
