> Even the smaller TL-15 safes weigh hundreds of pounds
I've seen a TL-15 safe that came as 6 separate modular pieces (i.e., 5 walls and the door each weighing about 100-150 pounds) that you bolted together, internally, with about 50-60 heavy bolts. It was specifically intended for condos, high rise offices, etc., so you could easily transport each piece on a hand cart or dolly, then assemble in place. It was a beautiful design, but no longer manufactured as far as I can tell.
