TD is right. They'll hold some for a while. Some till you get there. A big old male….. I hope the best for ya. They are brutal on smaller traps. They are hard on big, heavy traps. Being new, with good springs has nothing to do with how well they they will hold. if the coyote pulls and lunges hard enough to slightly bend the base plate, they will pull the jaws right out of them. Not to discourage you in any way John. Thats just facts. Use what you got, and catch em!!!! Good luck, and have some fun with it.
