Rated 5 out of 5 by from Indestructible toolbox I bought this toolbox going on four years ago. About three years ago I had a major rollover accident that resulted in a few broken vertebrae. In the accident this toolbox got thrown from the truck at substantial speeds and some how miraculously managed to remain closed and locked with my few thousand dollars of tools inside and only received one large dent in a crease on the lid and a couple broken spot welds on the inside of the lid. I still use that same toolbox to this day. I am a carpenter so it gets daily abuse and still functions properly. From that day I became a die-hard Weather Guard fan and refuse to purchase any other toolbox.

Rated 3 out of 5 by from Warranty is worthless A limited lifetime warranty should have something that it covers for a lifetime of use. I understand about normal wear and tear but welds should last a lifetime of normal use. The weld broke free on the bracket for the gas spring pivot point but since it was 7 years old it is not covered. It has been a good toolbox and one of the selling points was the warranty so I was willing to buy the premium price. If you think your product will only last 5 years then make the warranty 5 years and not mislead the customer. I would not recommend it because for the cost it's lifetime is not long enough.

Rated 1 out of 5 by from Rusts very quickly My first box for my F250 Super Duty had some paint drip issues, very poor paint job, bubbles on the top lid. company then sent a second box, rivets were very evident. Shows considerable rust after a year and a half. i'm the original owner and filed a complaint, I've only heard crickets. Manufacturer will not stand by there product. Limited Lifetime warranty is bogus, every corner where there is a weld has rust. . Second, the lock on one of the sides is faulty as well.

Rated 1 out of 5 by from Poor construction! Purchased 12-19-2018 from Amazon. First of all, I know how to weld, so I know what I am observing. Bought this from decades ago experience with the brand. This new one however being made in the USA fell far short on quality. The outside they did not polish after welding the corners and wire brushing them, they just clear coated over them. On the inside It is only tac welded here and there sparsely about every 12" and very poorly at that. I can tell you from experience, the welds will not hold for long. The lid will not latch unless you press down hard from the middle by getting into the bed of the truck. I am very tempted to return it as I have saved the box and not installed it as of yet..

Rated 1 out of 5 by from Worthless tool box!!! The box is great in size but the downside is that you are able to unlock the locks with a different cut key from another tool box. I found out the hard way. All my tools were stolen over night. i can confirm this because my company has 10 trucks with the same tool box and you are able to unlock the locks with all the keys (all keys have a different cut).

Rated 4 out of 5 by from Get a universal toolbox mounting kit Impossible to install on a 2018 F-150 with supplied hardware. There is no room to get your hand under the box to hold the brackets. I purchased a gripe-right universal toolbox mounting kit to allow the installation. Consider an upgrade to your hardware. Otherwise, great addition.

Rated 5 out of 5 by from Tuff box Heavy duty, Solid and Tuff. While this is the aluminum box, I thought it would be weak like so many competitors however I was very impressed with the thickness of the box and lid. I've had other brands and they bend or get dented too easy. I've only had the box 1 week but I understand the paint is coated to withstand for years so I am expecting this box to look great for a long while especially since I keep my trucks for 10+ years. I like the extras they provide, slide and compartment trays. I like the inset locks and are theft deterrent also the extra tie down loops on the front. This box was a bit more expensive than I wanted to spend, but now I see why, QUALITY! The box to truck fasteners they provide are tough to put in (wear gloves and/or use pliers to hold) or you might lose a finger when it spins lose. I am used to taking my truck box in and out depending on the load, I won't be taking this out, however this too may be a theft deterrent as well.

Rated 2 out of 5 by from Closing Mechanism failure I bought this online and had touble shutting the lid and it staying shut. I watched how to fix it from the website and that did not work. Hoping the company calls me back to fix the problem

Does the 121-52-01 box fit a 2015 Ford F150 with 5-1/2' bed? It is not shown to fit in weather guards "gear up truck fit guide", yet the full size standard version of the box 127-52-02 shows that it does fit. Measurements look okay for fit.

Two questions: 1.  There is one review that says that it cannot be installed on a 2018 F-150 without a separate universal mounting kit. True? 2.  Does the box have latches on both sides so that it can easily be open from either side of the truck?

Asked by: Bridgforth Rutledge
To mount the 127 box on a 2018 F-150, you will need the supplemental bolt kit number 70320. This kit is to help prevent galvanic corrosion with the aluminum truck beds. This box has latches on both sides.
