The K9 Extreme Jr trap feautes 5 1/4 inside jaw, 5 11/16 outside jaw, 1/4 main frame and 1/4 cross frame. It comes with two heavy swivels and heavy duty chain. The pan size is 3 3/8 dogless desgin. The K9 Extreme is a perfect trap for bobcats, foxs, and coyotes. Changing springs is a breeze with the 5/16 botls. The pan can be set 1/4 below jaw surface for perfect paw placement.
This trap is a tank. Very heavy built and easy to set. Pan sat level right from the start. Pan tension on the one I received was good. My trap came with the mainsprings mounted on the front unlike how it's pictured. That really helps with lowering the pan tension. Also my trap came with laminated jaws which was another bonus. Shipping only took a few days.
I gave it four stars simply because it is not easy to adjust the pan tension. The pan tension is very high initially and it takes a lot to get it right. Very sturdy trap though and I like how it is already dyed.
