I know I had seen somewhere in these pages a pattern for stackable 220 boxes. I don’t know what I’m doing wrong in the archives, but have never found what I’m looking for in there !
Can someone point me in the right direction?

Buckets stack
Lots of good stuff like this has been recently pruned.

Thanks tjm that u tube video will help , I think that was for a 160 . Will not take too much modification to cut them for a 220 !

just make the front big enough for the trap and the back smaller the same as a bucket is tapered and adjust to what ever trap you want.

UNIVERSAL CONIBEAR TRAP BOX(Stackable)

This rotating jaw trap box will accommodate a 120, 160 or 220 size trap:
Why a trap box that will accommodate different size traps? One box can be used for trapping various size animals from mink/marten to fisher, coon and possibly bobcat. Also where trapping for marten, and fisher can be expected, the larger front opening is likely more inviting for a large fisher to enter.
The box length is 14 inches and the sides are made with 5/8 or 3/4 inch material. The front opening is +/- 9 1/2 inch square and the back about 5 inches square. Two finishing nails are used up through the bottom at the back to impale the bait on. The spring slots are 8 1/2 inches deep and 1 inch wide. The design/dimensions work out to a perfect distance for a 120,160 or 220 to be placed from the bait to provide a good neck and suitcase strike virtually every time when using the appropriate trap for the species targeted. I made them to accommodate a 220 just to save on boxes. Depending on the target animal you just use the appropriate size trap and another size box is not required.

That’s awesome tomcat , just what I was looking for !
Have you ever set a 220 and a 120 both in there ? I only ask because I caught a big coon last year and had another one come in behind and steal my bait can, lol !

No.

Would I be right in thinking the first trap ( the 220 ) would not fire the second trap ?

I do not know' just try it.

That is a great design!

I like that design. Thx for sharing
