Pay attention what Kirk DeKalb said about the 1x2 wire mesh. It's not strong enough to hold them. Otter or Beaver. Needs to be 1x1 14ga. Because you don't want to catch him and have get out. You never catch him again.
I assume you guys mean for a land set because all my swimthtrough traps are built with 1x2" wire and they've caught dozens of beaver and a few otter without any problems
