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

This is one of the least expensive trailer boxes I could find, so I was expecting it to be OK but not great. I was pleased to see that the plastic is heavy duty, the box is lightweight, the hasp fits securely, it is water proof (i.e. rain proof). It has some diamond pattern in it that makes it attractive, and the amount of space inside is ample for stowing misc trailer gear. Installation was easy; it only required drilling four 3/16 inch holes through the box and trailer frame. Install hardware is included.

Very nice box. Worked out perfect for the tear drop trailer I am building. Will mount the battery in the box. Lots of room. Well built and a very good price.

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.

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.

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

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.

Solid and priced right

Very excellent quality! My husband is thrilled with it! Shipped quick too.

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

Suits my needs and appears well built. The supplied mounting lag bolts could have been stronger, one of them snapped during the install and I had to drill it out and replace.

Nice attachment for my trailer. It's light but sturdy
