Tool box is nice and light. Made out of aluminum and big enough to put all my snow chains (8 in all) I decided to only put 4 chains inside to leave room for straps and other things. I have it on the catwalk behind the sleeper of my truck. It was easy to drill holes in the bottom so that I could put bolts with washers, lock washers and a nut. Looks great, comes with a couple keys to lock. easy to open and close. It's worth every penny I spent.
