The MB-650 Coyote & Bobcat trap is Made in USA with no foreign parts or material. The MB-650 is 4-coiled, base plated, center swiveled, and an extra heavy duty oversized pan which provides for a huge kill area. The pan tension is adjustable with a #10 brass pan bolt. Both heavy jaws are held down by the trigger system which will keep any animal from flipping up a loose jaw. The dog has a "step-down" notch milled into it that gives you an audible click when you're lowering the pan. MB Crunch proof swivels have been installed with heavy duty machined chain. Features Inside Laminated 1/4" offset jaws.
