A little bit of boredom today so here’s how I make my fenn trap boxes. I’m sure some people won’t like them but some people will like them, but it works for me and if it helps someone else out then it’s all good.
The little V notch in the side is to locate the safety hook in. This lines up the trap perfectly with the wood on the bottom which makes the trap sit flush and gives the box a bit of strength. I find using just 3 lengths of wood it’s a bit flimsy
