The DONGCHENG HD071004 4 Inch (100 mm) Heavy-Duty G-Clamp is made for carpenters, welders, fabricators, mechanics, and DIY users who need a firm, reliable hold on larger work while cutting, gluing, drilling, or welding. The screw spindle opens to 100 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 wider opening handles thicker stock and bigger assemblies than the 2 inch and 3 inch models.
