Here's the chain setups for you Bottomline.
These are a couple popular chain setups w/shocksprings I've done up for a few trappers.
The top chain setup is made with #3MB heavy duty chain,30d nail swivels and an MB crunch proof end chain swivel.The shockspring is a JC Conner T-Bar,instead of the stock washers that come with the T-Bars,I use a,I believe a 5/8" lock washer.What the larger washer does is give more freedom for the heavy nail swivel to move around,with no binding.
The setup below that is the same,except for it's #3 twist link chain,and the T-Bar is on the end instead of the mid chain or 3/4 chain.A chain setup like this is virtually coyote proof.Lengths can vary,these ones where made for 24" total length.J hooks are welded shut.

Here's a close up of the washer and swivel connection,this one is a 40d nail swivel.

These are good setups for coyotes,but still can't prevent this,lol.
