My Yote traps are Duke 1 3/4 offset four coils. Trash their chain and swivels put on two MB crunch proof swivels, eight inches of #2 straight machine chain, double stake swivel, two 18 inch rebar stakes, never had a problem. I also change the pan bolts and file everything smooth.
That's great used to love trapping them but haven't seen one in 16 years. Started trapping more coyotes about the same time we started seeing less greys. Hope they make a comeback.
