I get them in marten sets. They're pretty good at getting through a conibear, but #0 and #1 footholds seem to catch most of them, I have less stolen bait when I put a foothold on a pole than when I put a #120 in a box

I would run pans or the trigger wire in a T shape set with the dog down. So the T is upside down. I would have the bend about 1 inch up hoping the weasel would jump it and push off it. The inch would include the metal bracket height. I would have a trap in both ends and not have bait on the trigger in a box.

You can use 110 on pole set.

I select a small pole to prevent coon and fisher from climbing.

I use a piece of deck board which is nailed to the pole. I use a small piece of 1/4 in mesh which I fold around a small piece of beaver or muskrat. A leave a piece of bait sticking out of the mesh and insert it to the 110 trigger.

I cover the trap with couple spruce branches to shield the trap and to keep the birds away. You may end up catching a red squirrel, but whatever.

I don`t normally target weasel but will do the occasional set if I see signs. It has worked for me.

Good luck!
