The Heck Industries C-2.3 Fixed Angle Welding Clamp with 2-3/8" maximum opening, 1-3/8" jaw height, and 4-1/4" jaw width holds components at 90 degrees for accurate joint welding. The clamp's rear jaw swivels and is self-centering to accommodate different workpiece sizes. The clamp is made of cast iron, which provides strength and durability. It has a copper-plated spindle to resist weld spatter and includes slotted holes for bench mounting.

Welding clamps hold components at specific angles to each other to facilitate welding and other assembly operations. They are either variable angle or fixed angle. Variable angle clamps can be adjusted for welding joints of two components at variety of angles. Fixed angle clamps hold two components at a 90-degree angle.
