The Profax-Lenco GC500 LPG clamp is rated at 500 A and features a 2-inch jaw opening, with both jaws made from high-copper alloy to carry current. Serrated upper and lower jaws provide a firm bite, while a durable brass hinge pin allows both jaws to conduct. Its oval-point screw cable connection accepts 3/0 to 4/0 AWG cable without requiring shim stock or a pressure plate.
