Video Transcript for DeeZee Trailer Cargo Organizers - Toolbox - DZ77 Review

Today were going to review part number DZ77. This is the DeeZee Specialty Series Underbody Toolbox. This is silver in color. This underbody box is ideal for storage under your flatbed truck, your dump truck or your trailer body. Its made of a rust proof bright tread aluminum construction. It is rectangular in design and again, is an underbody style.

It has the single dropdown door. As you can see it drops down from top to bottom and it has the chains on each side that prevent the lid from totally falling down. This will provide easy access to the cargo inside your toolbox. Here you can see the stainless steel locking T handle latch. You just turn it and push the handle out of the way.

That would keep the lid closed. It can be locked. It does have the two keys here that should just turn it, turn the keys and lock half way. The handle will still open, but it will not turn to release the lid. To open it just turn it the other way half a turn, that will allow you to twist it and open your lid.

You notice right here it actually has a water tight C channel that goes all the way around. On the very front here is a foam bulb seal which will prevent water from entering your box and damaging anything on the inside. This is a very simple installation. This mounts to the underbody of your vehicle and it is required to use the DeeZee Universal Mounting Kit that is sold separately. It is part number DZDD-2502.

Its basically two L-shape brackets that will mount on each end and allows you to bolt it up underneath the body of your vehicle. This part is made in the USA. A few overall dimensions on this, the overall length of this toolbox is 36 inches. The width is going to be 20 inches. The actual height is about 18 inches. The interior capacity is 7 cu ft of space on the inside. This does come with a limited lifetime warranty. Again, just to show you, you close the lid, twist the handle about a quarter of a turn, push it down it keeps the lid in place. To lock it, just turn this lock half a turn. It even has a nice little cover that will cover the lock itself to prevent any dirt or grime from getting inside the lock. That should do it for the review on part number DZ77 the DeeZee Specialty Series Underbody Toolbox.

Review from a similar Specialty Series in Trailer Cargo Organizers


The box was received undamaged in good condition. I am attempting to use the box for my batteries (Currently, two large grp. 34 deep cycle) and it turned out to be a bit larger than the location on my trailer tongue; I am moving the Propane bottles as much as I can to see if it will work. If I have to, I will modify the box to allow the batteries to slide out one end. I would have liked to find a box already available that way, but couldn't. But, back to the review, the box was what I ordered, unfortunately the location of use was not what or where the box was designed. I will follow-up with pics when the final installation is complete. 691520

Great box and very solid! I am mounting it on my car hauler trailer to hold two batteries to power the winch, and trailer toung jack! I put plywood in the bottom to protect the batteries. I am very satisfied with the product!!! 699133

Product does excatly what I want it to do Houses my propane Tanks and Battery with room to spare. Hopfully they won't get stollen again... 52386


Comments
Be sure to consider that adding heavy items generatorbatteries,etc. adds to the tongue weight and towing towing capacity limits.

Great deal. Purchased at "dinged" version of the product so paid about $87 vs. $290 for undamaged product. Dinged version was noted as "everything works", and it does. About 10-15 mins of gentle banging and twisting it looks as good as new, after a little bit of use. Nothing stays new forever. Winch and battery fit inside on the bottom nicely, will install a a pull out shelf/tray above the winch/battery for storing tie down straps and bolted a solar trickle charger on the lid to keep battery charged. A nice piece and a cost effective find for me. Thanks. 555222

Product worked fine for my limited space on the front of my trailer not ATV. Even when box was on backorder they direct shipped it from manufacturers. Great communication and split shipped one item. The lock fit perfect on my old T-handle box. Thank you for the email updates and the website order tracking links for each item. 549047

First, I like it a lot. There is lots of room inside, it meets my needs and I would buy it again because I think it is a very good value! Cons, Steel latch which means 3 months outside and it is already rusting. (I will eventually replace with a marine grade.) The unit is very strong on the outer sides, but not so much in the middle. I am 200 lbs and can stand on the outer sides of it, but I would not try to do so in the middle. (Note - Manufacturer does NOT recommend standing on it at all and I am not suggesting you do!) Depending on your specific trailer frame and what you intend to put in the tool box you may need to add some bottom support. You can see where I added a support bar in the front. If I was doing this mount over again, I would add a support or 2 in the middle because a couple of spare axle hubs and a bottle jack are causing it to sag significantly. 446689

Fits 2 group 31 batteries with room to spare. High quality box that looks and works great. The box does not come with battery hold downs, which I prefer because I could mount the batteries any way I wanted. 310472

This product was exactly what we were looking for. The description and picture sold us on the product. Its a very sturdy and rugged tool box, something I know we'll need for the type of work we do. 116235

Its still been a great product to have. We have used it throughout the year, loading it with all of our chains and binders. Its held its ground versus all the beatings, but unfortunately had to be replaced by our welders, they burned a hole in it when they were repairing the trailer jack. They replaced it with the same product, but Im not sure where they purchased it from. Either way, its still been a tough and ready to use product, and has come in handy multiple times on the job site.

Review from a similar Specialty Series in Trailer Cargo Organizers


I use this on my custom teardrop trailer and I really like this tongue box. One year later, this is holding up well. The only thing is that the lock hinge started to show a little rust almost right away, but it hasn't progressed too much. It was a little disappointing though. That said, I love that this has a padlock instead of having to use yet-another small key (I already have 3 just for my teardrop). It wasn't something I considered originally but figured out as soon as I put my combo lock on it. I do really like this tongue box. It was the perfect addition to my teardrop build. 563230

Used this box to replace the beat up distorted truck box I had mounted on my trailer and happy to say it’s holding up excellent to the same abuse. Aside from it exceeding all my storage needs I also find it to be a much better fit functionally and appearance wise for my trailer. 548075

Boxes arrived in 3-4 days. I got used ones and was very happy I didn’t pay the full price. They work fine just a few dinges. I painted the inside white to see tools easier. The boxes are aluminum, seems very light duty. I wouldn’t step on top of it. When you close the top, the sides flex when pressure is put on the latch. I would have preferred a heavy steel, but needed a small box for the location and this was the only one I could find. For an ATV it might work ok. Overall pretty happy- I just installed so we’ll see how they hold up over time. Next time I would look for a heavy steel one. I paid for 2 used ones the price of one new... to me a new one would not be worth the price they are asking... just too light duty. 772550

  • Recommended Utility Chest To Secure Equipment Or Tools
    The DeeZee Specialty Series Underbody Toolbox - Steel - 6.75 Cu Ft - Black, DZDB-2601, is a very strong box. This box is very heavy weighing about 95 lbs. It will definitely keep your expensive equipment secure, but it won't be very easy to move without handles like you mentioned. Another option for you would be a black aluminum option like you mentioned. For that, I recommend the DeeZee Red Label Truck Bed Toolbox - Utility Chest Style - Aluminum - 6.4 Cu Ft - Black, # DZ8537B. ...
