Is the door in good condition? The condition I’m talking about is the inside and the fire proofing, is it cracked or loose . Is the bed pan were the lock mount still welded to the frame work of the door?
To test this door, open the door and frame into a V so that it is free standing. Take the top edge of the door and wiggle it. look at the lock area and the fire proofing to see if any of it is loose or broken away from the bed pan. Any questions on installing or testing you can PM . Thanks TJ
