  • Nice box but poor packaging
Size: 14 x 12 x 24
Like all Byers product this frame mounted storage box is excellent quality and should last a lifetime. My quibble is with the lousy way it was packaged. It came in a tight fitting cardboard box with one 3" wide strip of paper thin foam wrapped around the middle of the item. This foam was not adequate enough to keep the sides of the box from rubbing on the cardboard and as a result all 6 sides of the storage box are burnished as if someone took 220 grit sandpaper to it. I guess I'll have to hit it with some black Rustolium before installing it since, if I return it, with their poor packaging, the replacement will probably be the same or worse. ... show more

  • Solid construction and weather-tight
Size: 18 x 18 x 36
Solid construction and weather-tight—great value This underbody box exceeded my expectations. The 14-gauge steel feels sturdy and well-built, with a durable powder coat that holds up to road grime and weather. The T-latch locks tight and gives a secure seal—no water intrusion even after heavy rain. It mounted easily to my trailer frame, and the space is perfect for keeping tools and straps organized. You can tell it’s American-made. Definitely recommend for anyone needing a tough, secure truck or trailer toolbox. ... show more

  • Well built compared to others I've had
Size: 18 x 18 x 60
Heavy built. Be sure to have an extra set of strong hands. The size is perfect. I installed the tool box on a stepdeck trailer. Plenty of room. I'll watch the screws and rivits. Gotta stay on top if those, my other toolbox they started to vibrant out. The key lock seems a bit tough to turn. I'll lube the locks to see if that helps. Overall I'm very happy and wish I'd have bought the buyers box first. So far no dirt is getting past the seals. I'll keep an eye on it and update later. ... show more

  • Heavy duty, need team lift for install
Size: 15 x 13 x 48
This box is awesome! It's heavy AF though. My FedEx carrier likely damaged one of the corners getting it out of his truck, but no matter because it's hidden on my install. Really like how the tightness of the closures are adjustable. I put this under my shuttlebus conversion. I am a 5 foot tall female and installed this by myself using a floor jack to lift it into place. I used 1/8" thick 2" wide steel bar which I had to drill holes through to mount to the box. My channel rails are 14.5" apart, so since the OD depth of this box is only 13" I mounted 12" bars to the inside of the box and 16" bars in the outside (see pics). I put 3 bars on the box to hang this from the channel rails that are welded to the frame cross beams under my bus. Sturdy AF! Love this box, plan on getting another one for the opposite side of the bus soon. Removed an AC unit I never used to put this in and used the same bolts and channel rail do-dads to hang it the same way the AC unit was hanging. Love it! Only complaint is I wish they would use foam pads on the corners when they box it up for shipping. Almost all the reviews including mine mention corner damage during shipping. It's obvious that the manufacturer provides the packaging, so it is not the seller's or shipper's fault for damage. It didn't matter though, I am extremely happy with it. ... show more

  • Quality Welds / Sturdy Thickness / Quality Handle
Size: 14 x 16 x 36
I searched quite a bit for a tool chest I could install in my 2017 Jeep Wrangled Unlimited cargo area for secure storage solution with the top off. I wanted to have a front opening and very sturdy chest and the underbody seemed to be the best solution for me. Slightly u conventional use for this, but it works perfect. This chest is very sturdy and appears to have quality welds. There was some slight bowing on the sides likely due to the welding heat, but not significant enough for me to dislike it. I did adjust the door slightly on the hinge to center it as well. Overall very happy. If I had one recommendation for the manufacturer it would be to make the lock easier to get the key in. It seems it is a bit hard to get it in since it has the little cover to protect it from ambient conditions ... show more

  • Lacking quality for a USA made product
Size: 14 x 12 x 18
I had to return the first set because of big dents and scratches, second set had the same dents to looks like it’s a manufacturing issue, also the lid is not straight, it’s crooked on all 4 units I bought, and the gaskets are cheap and one after just 1 week one gaskets already peeling off. Build quality is worse than China, welds are terrible they didn’t even bother to grind them down, take the proudly made In USA sticker off, it’s not deserving of that. Whole reason I bought these is because it’s American made. Better off buying the China vevor brand , my buddy had those and it’s 2x the box for half the price. Will be returning….again! ... show more

  • Perfect enclosure for EU2000i Generator
Size: 18 x 18 x 24
I purchased two of these based on a video online that shows that the inverter EU2000i generator fits perfectly inside and it did. I just verified that the generator fits inside. The second I purchase will be use for an extended fuel tank. The reason I need these is to keep my generator and extended fuel tank from being stolen. As these will be outside my house. I do plan on drilling holes on one for the generator to have adequate ventilation. Probably enough holes to not need a fan or fans. I am very happy as these are so strong and seems to be of high quality. After hurricane Ida, I feel better prepared if another storm decides to develop. I will have peace of mind knowing that it is safe. I do plan on chaining them together onto a concrete column for added security. Thanks. ... show more
