Measures 21" wide, 24" deep, 39" tall. Lots of space. Painted grey, in decent condition. It's 1/4 inch steel on the sides with a 1/2" inch steel door. Moveable shelves. It has a safe deposit box type key (which I have, and which works). Lock mechanism secures the top, bottom, and side.
This is more of a strong box than a safe. It would definitely slow somebody down, but it doesn't have thicker walls or fire protection. On the other hand, while it still weighs - guessing here - about 250-300 pounds, a decent safe of the same size would weigh 800-1000 pounds or more. So this thing is a little more flexible in where you can put it.
YOU MOVE. It's in a shed in my back yard and not complicated to extract. Nothing in the way. Just sorta heavy. Two fit guys can probably swing it, but third would be helpful.
