If I wire off from a cinder block will it hold a coon from dragging it off?

I've done it a couple times, it's held but they will drag em if the coon is big enough. I got worried if I caught a bigger one it might not be enough. Started using old tires, the big ones drag em a little but there's enough give in the tire so the cable isn't cutting into it

We don't have big coon here, but our 15,16 pounders will merrily drag a cement block until it fetches up on something.

It should

All blocks aren't equal. If by a cinder block you mean Haydite ,it's the lightweight version of a concrete block which will be way better. I think a big boar would drag a Haydite one till he got hung up, maybe somewhere you don't want.

Thanks. I see what I can do with the situation I have.

20 years ago I set a Colvert pile loaded with coon tracks it was a hwy. I couldn't steak the trap in the steel pipl and the sand would not hold so wired it off to a 12" block that was there. Had a 3x sal the next morning and she drug that block 25 yards and there was a 5' wide area she went back and forth pulling that had zero river cane left and looked plowed up. Yes it was sand but I was impressed. I was going to let her go but didn't have a catch stick. Her bad mood is how I know she went 3x.

The will work as a drag but I try not to use them having seen several break easily. Figured I don't want to loose my traps.

In the above case the Colvert was 4' and I used the lock to block part it it off and fence them over to my trap

Yep, will do something different or use 2 or 3 of them.

I have used them but have had a few big coon pull them father then I thought

Blocks are great drags .... Easy and simple like trappers....

If it don't it will leave a pretty good trail.
just

It matters how it's laying. Turn it with the holes up and down. It might get turned over but it makes a difference.

I use blocks around ponds for coon, and have yet to have one dragged off, usually the coon is waiting for me with it's head stuffed into one of the holes, fast asleep. Can't say the coon were especially large tho.

Using DPs or regular footholds?

If regular footholds....need to consider a non-target such as a big coyote or bcat getting in it.

Always anchor for the biggest possible critter.
