The above three posts are correct. You can do what you want. But, the same stop you put on them for domestics will also work for coyotes. Not a good idea unless you want to loose and educate a few coyotes. If you give them too much time to get out, they will. They WILL chew through a cable restraint. I want them tangled and incapacitated in short order.

If your washers do not easily relax, you might want to be sure your cable diameter is compatible with the holes in the washers. Not all cab;e is the exact size as advertised, and could be a tad big. If that is not it maybe bit of rust, paint, or even dye can keep them from opening up. Work the washers back and forth on the cab;e several times and see if they loosen up.
