Ok this always ends up being a good debate. I like to have options. I have areas I can’t use drags or I can’t use earth anchors or I have to tether off with cable to a tree or something so I like to have a quick link on all my traps so I can have options at each set.

So what attachment methods do you use? Quick link, split rings, j-hook ( just open and close with pliers) . Post up what your tried and true method of attaching anchoring systems on the fly is !

I dont usually cable off to trees at all, either a super stake or a drag. So my traps all have 18" chained super stakes with every s/j hook welded, then all my drags have 8' of #3 chain with a quick link. If I want to use a drag I just hook the quick link on the end of the trap chain right at the super stake and viola, done

I have zero faith in a used J hook for coyotes. I do have a bunch of them in a jar that I may use at some point for coons or if I weld them.

I have 3/16 quick links on most of mine and have only had 1 failure.
That was me putting way more force with a stake puller than a coyote could
Also when I learned to pull on the anchor side of the quick link

I have not used a drag in a long time but I have some.
They all have double loop / swingset chain that will be replaced before I do use them.

Lost 1 trap because of that type chain

Only thing I cable directly to trees is DPs and I just loop cable through eye on one end and use a small quick link

I tighten all quick links with a small adjustable wrench and a pair of pliers

Quick links.

Never had one fail on an animal.

I can stretch them out enough horsing on them with my big puller where you can’t screw them open anymore.

3\16 quick link.

Split rings ......... changing anything is fast. Never lost a bobcat or coyote due to one failing. If I was trapping wolves or lions I would probably weld everything shut.

3/16 quick link on all of my land traps. I cable off on tree's and clogs in the woods, to many rocks for earth anchor.
Water trap's get 1/8" quick link.
I had two 10' chains I left in the woods attached to trees that had been there for 5 years, I turned the nut on the quick link to loosen it and I was able to turn it the rest of the way with my fingers

I have a similar setup on my wolf traps, 36-42" of chain from trap to super stake, with three swivels. Drags have 8'-10' of chain. #5 chain on my traps, mostly #5 but some miscellaneous chains (all as heavy or heavier than #5) on my drags. All swivels welded and S hooks or cold shuts attaching the earth anchor welded. I use a 1/4" quick link to attach drags, or a length of chain to chain solid to tree. Often I just loop a drag around a tree and hook it solid, but I usually have a couple spare lengths of chain along and I sometimes use them to chain solid to a tree. My coyote traps are a little more varied, they all have earth anchors attached also, and all swivels welded (we have wolves, I don't want one opening up a J hook) but the chain may be #3, or #5, or some from cut down tire chains. And some of those traps are short chained with as little as 6" between trap and the swivel attaching the chained earth anchor, (22-24" from trap to super stake) and some may have as much as four feet between trap and swivel attaching the earth anchor chain. A 1/4" quick link will not fit through #3 chain, a 3/16" will but if I am anywhere there is any possibllity of a wolf showing up, I will use two 3/16" quick links.

I should say, I have I think 10 MB 750s and one Sleepy Creek 4 1/2 that were my first wolf traps (used to have two 4 1/2s and a dozen 750s, set up like this, but three of those traps have been stolen) with 8' of chain attached and a chained earth anchor Ying of at about the 30" mark. After I used them a year I realized that chain attached to the trap was unnecesssary, and if staking the trap was a pain to deal with.
