thanks. It used to be a turtle aquarium that that was fiber glassed. We had to cut it in half to get it through the door. the hide has a slide door that can be open and closed from outside the enclosure (that seperates the hide from the main area) with a door on each end that has 2 bolt locks and a paddle lock on each door. Like I said. He is safe but the 45 is for worst case kinda thing
