K.O. # 1.5 CS is a coilspring trap. The K.O. trap is built for strength and it features a heavy 3/16" frame, 1/8" cross frame and 1/8" jaw levers. Unlike most traps, the frame is welded not rivited. The levers and jaws are also heat treated for strength.  This trap includes a heavy duty double posted flopper pan, a pan stop, extra heavy duty chain and two swivels, a rounded and deburred dog.  Also added is the new wicked K.O. # 2 springs which are smaller than music wire springs but stronger.
