Dee Zee DZ91717P Poly Triangle Trailer Box 36 x 18.75 x 18 inches, 25 lbs

Great for utility trailers. Love the size, it’s huge! The box is made of a very durable and sturdy thick plastic (went with plastic because they don’t rust.) has a latch for a padlock. Looks great on my utility trailer. Allows me to store 2 sets of wheel chocks , 4-6 ratchet straps, a cargo net and still plenty of space for tools/oils, etc. The only thing that could have made it better is that it does not come with any hardware. I used square U-bolts, just remember to seal the clamp holes with RTV or something. Other than that, super functional, I love it and a great buy. No regrets and would buy again. Highly recommended.

I mounted this box in the nose of my 7x16 utility trailer and it fit just fine while allowing room to crank the landing gear and room to swing the lid open. You do need to leave a 1.75" gap between the back/hinge side of the box and the rails on your trailer because as the lid opens the hinge design pivots the lid back. So to reiterate, if you pushed this back against a solid object and went to open the lid, you can not. You may want to do as I did and use square U-bolts from to better attach this. I would never wish to drilll into my frame and use the DeeZee provided self tapping screws, but you may do that as the instructions show. The box is huge, you can fit much more into the box than the average person would even want to keep stored in a trailer box. I'm telling you, this thing is large! The box is quite strong once installed, I am 185 lbs and can stand on it with no noticable flexing. It's easily able to handle any average built man standing on it occasionally if the need arises. This thing is awesome, go ahead and buy it.

This tongue box seems ideal for our needs. While it doesn’t seem the sturdiest thing in the world . . . so far, even in cold conditions, it’s been holding up. I pre-drilled holes in the frame and unlike other commenters, my bolts didn’t break. I expect they didn’t pre-drill. At any rate, I house my deep-cycle gel-type battery (in a box), my wheel chocks, (4)1 pound propane tanks, My 20 foot 10 gauge extension cord, a jack, and a battery switch, and 50 amp fuse mounted on a wooden panel I installed on the inside back of the box. I’ve also run my battery cables through the back of the box which I goofed up with silicone caulk and those intern go through a gland into my trailer. All in all, I expect I made a pretty good purchase with his tongue box.

While it isn't as sturdy as a much more expensive box, it isn't as expensive either, and it certainly seems sturdy enough for recreational or homeowner utility trailer use. I added it to my teardrop trailer, where it will likely carry wheel chocks and other trailer tools, tarps and related supplies, keeping them out of the tow vehicle. On my trailer I either needed a triangular box or a very narrow square one in the limited amount of room between the hitch coupler and the teardrop, and this one uses the space well, offering quite a bit of room in it. After reading other reviews, I decided to through-bolt the box to my trailer arms rather than use the sheet metal screws that came with it, though I did use the fender washers which seem important to distribute the pressure of the screw/bolt over the plastic surface. I also applied a good amount of marine silicone caulk to the holes to keep the interior appropriately sealed up from the weather. I would have gone to five stars -- but mine arrived with a dent in it that I had to push out and heat with a hair dryer to encourage the plastic to return to its original shape -- but that worked well, the dent is now gone, and I have a trailer box that fits, has a lot of room, and should last quite a while for my periodic use. If you have a commercial use or are planning to use the box to store anvils, barbells, and sledge hammers, you'll likely want something more robust (or at least install a hard surface under it), but if you are planning to use it for general gear or other applications that aren't too abusive, this should be fine.

Solid and priced right

I added this to the frame on the front of my trailer to act as a catch all for the many different things needed while camping - extension cords, chocks, fire equipment. I had to weld a bracket so it would work for my situation, but if your trailer has appropriate crossmembers, this may not be needed. The box is lightweight, contains screws and washers for mounting and has been watertight for me. I did add plywood to the base of the box for increased durability, but it certainly is not needed. I also added additional hardware to ensure it was perfectly stable on my trailer. It has been fantastic for me. I know some people do say that the locking clasp is cheap due to the fact that it is riveted onto the plastic, however, you could drill out the rivets and install screws/bolts if necessary. My lock will keep honest people out, however, if someone wanted to get into the box, it is still plastic! It does what it's intended to and that is to keep my items clean and dry while camping.

Product arrived quickly and was as described. Didn't realize it included the mounting hardware, which was a nice surprise. I purchased this after returning the one that is made in China. That one is similar and cheaper but far inferior, and it did not include mounting hardware. This product is made in the USA and it shows. The Chinese made box didn't close all the way due to the poor design which would allow water to get in the box. The Dee Zee box lid closes all the way sealing out water and has a nice quality hasp on it for a lock to be added to secure it. It fits nicely on my 6'x12' trailer. I do wish it was a little bit wider but it is probably designed to fit an 8' or 10' trailer perfectly. Overall though, it is a great product. Would definitely buy again.

Sturdy, well made, has a lock …holds many items Recommend this!

Buena calidad y se instala fácil

I really like this trailer storage box. It's not heavy like a metal one but it's solid. You can stand on it (not sure why you would) and the plastic is fairly thick. The inside is large enough to store all of your trailer stuff.. (straps, shackles, chains etc.) I was seriously considering building a storage box out of metal but for the time and cost.. It really wasn't worth it, unless you have or are building a dump trailer where you will have hydraulic pump and tank. This will work fine for other trailers. (NOTE) This may not fit exactly on your trailer tongue. The cover also opens up slightly outside and leans back several inches.. Keep in mind when installing. In my case I set the box up and made sure when I opened the lid it didn't hit anything then.. I welded angle iron recessed across the tongue to support the front and back of the box with a flat bar welded across the middle for added support in the center of the box. I pre drilled holes in each piece before welding in place on the tongue then all I had to do was place the storage box and drill holes up into it through the pre drilled holes. This made a really good and secure platform. Hopefully this helps.

excelente
