  • Quality Product, well worth the money!
Size: 24-inch Color: Black
I was a little apprehensive after reading some comments on this box. It arrived in perfect condition and three days early by FedEx. Care was taken to package the metal box. I inspected it after removing from the shipping box and found no blemishes, dents or anything that would cause me to return it. The door was square with the opening, the lock works fine and two chains keep the door from opening too far. I AM A HAPPY CAMPER! I mounted this on top of the Stromberg Carlson located in front of my Casita, Freedom Deluxe, Travel Trailer for the purpose of carrying needed RV supplies like fresh water hoses, water filter, valves, electrical box plug, wheel chocks, scissor jack handle, and small tools. In other words, stuff that we do not want in the TV (Tow Vehicle) and have no room for in the Casita because let me tell you it is compact inside there. Casita owners will understand. Thank you Arksen for a quality product delivered to my door. I might add that it is the only lockable tool box I found that would sit inside the Stromberg tray without modifications to the tray.

  • Good storage

Great purchase! Heavy duty and holds a lot of extra stuff for the semi!

  • It a very light tool box
Size: 24-inch Color: Silver
Great Little Storage Very attractive price, but i didn't mount on the truck, instead i mounted in my garage but you will need to turn it up side down before install so you can open it easier. Comes with lock and keys as a bonus. Not a super heavy duty tool box, but it's good for regular duties.

  • Metal is thin, flexible. Finish is relatively cheap.
Size: 24-inch Color: Black
I would not use this to store anything over 15-20 pounds of gear. I have it mounted on the back of my camper van to hold recovery tracks, straps, etc. The competing boxes from van gear manufacturers are $398 and $620. The box is okay, but very then and flimsy. I mounted with 4 u-bolts and some 1/4" aluminum bar stock as washers inside. I have recovery tracks mounted on the left side of the box, using full-width aluminum flat stock on the inside as reinforcement. The end result is a semi-rigid box that is at least 80% cheaper than the equivalent in the van conversion industry. That said -- those boxes are also all aluminum, yet they are 50% heavier. Metal thickness and powder-coating are two qualities that you are sacrificing with this box. This is the kind of toolbox I'd put on a cheap trailer, but definitely not underneath my flatbed. I need to play with the latch assembly to see if I can force this to close tighter -- I would 100% not trust it to be truly water resistant. ... show more

  • Both keys match, rubber gasket is good. Light duty, looks solid.
Size: 36-inch Color: Black
Very light-duty / thin. Good for life jackets, bike helmets, kid's toys. Paint and diamond plate pattern make the box 'look rugged. The door chain feels like plastic, and seems barely strong enough to hold the door. -- It is a perfect addition to a tent trailer or small camper for added exterior storage. ... show more
