several years ago when ammo cans were $4 - $5 , I bought a few , installed hasps and used them to lock up my ammo .
I converted one of these for a Moultrie Lock Box ( don't think much of any I saw in stores ) . I cut a hole for the face of the camera to do it's thing . Found a thick piece of solid styrafoam for a filler . Installed a couple of eye-bolts for mounting and then added a Waddell Top Plate at the base of the back of the camera for adjustment . Now I have to field test it .
