Hi Guys I manufacture larsen traps made from 2"x1" timbers professionally jointed pilot holed and screwed with exceptional finish. Each trap comes with 1"x1" 16 gauge galv weld mesh and is very strong stuff... i use these traps myself and have sold alot to pest control friends gamekeeping friends and farmers in my local area. Each trap has a half covered call bird compartment with a perch, and 2 catching conpartments. The traps can be made on legs if you are struggling catching crows or just wish them to be off the floor, this also helps in preventing the timbers rotting. These traps are sound
