Great fire proof boxes. Took 34 boxes of files and they fit into 25 of these fire proof boxes. Stack 3 high - worked great

Excellent Document Storage Unit

from South Carolina

This holds a large amt of documents and files! It is heavy enough to be durable, yet the size is not too bulky. The hinge locks are easy to manipulate.

light weight storage box

from Oak Park, IL – Verified Buyer

I needed a box for my important documents, but everything I found was extremely heavy. This box has plenty of space for all your vital documents and it's not impossible to move. I hope I never have to test the limits of this box, but if anything ever happens flood or fire, I think it is quite sturdy.
