DEFENDER SERIES 300300-53-01 Standard Lo-Side Box 60 x 16.7 x 12.9 Black is rated 3.0 out of 5 by 3.
Rated 5 out of 5 by from Great Box for the price Great box for the price, not as good as the premium weather guard boxes, but it is $300 less in price.

Rated 1 out of 5 by from Very disappointing I was looking for a mid-range box that wasn't too light and junky but wasn't real expensive either. I was very excited to see that Weather Guard seemed to be offering just what I was looking for with your Defender Series. Unfortunately, there is no defense for the lack of quality in this tool box.The first one arrived with a big dent in the bottom corner and the top dented from one end to the other, with the keys locked inside (it appeared I wasn't the first to return it). Amazon sent me another one and gave me 30 days to return the first one. Second one dented less, but still not acceptable. Amazon to the rescue and I got my third box, which only had one dent in the top that looked like somebody had hit it sharply with a ball peen hammer. Better than box 1 and 2 and maybe I could live with it, although it was still a lot of money and already dented. I am not easy on things, but the one I am retiring from a smaller truck didn't have any dents as bad as that one. As I looked it over deciding whether to keep it or not, I noticed a few other things. When I placed the box in my truck, I noticed that the sides of the box were not parallel. If I lined up one side, the other ran off at an angle. Then I noticed that the rods between the latches had no cover over them and would definitely be getting pushed against by contents in the box, making it hard or impossible to open. Even the cheapest boxes cover these. Then I realized that the reason the tops were always dented was because the aluminum was so flimsy. I know I was slow to catch on to this, but I was blinded by the Weather Guard name that I thought meant something. When they arrived dented, I initially blamed the lack of protection in the shipping box, but then I realized that if you have to cushion it and mark it "fragile" in order to ship it, well it's not a very rugged tool box, is it? It is not a box you could stand on, or even set something down hard, without denting it. One of the big selling points for the box for me was the fact that you could push the button and the lid opened, enabling you to open it with your hands full. But because the box was so poorly made, the cover hung up on the box about half the time, requiring a push to get it to open.You also can't latch both sides securely by pushing down on just one side of the cover, requiring a trip around the truck to push down the other side. The bolts on the shocks were about to fall out, the flimsy aluminum partitions were bent...I sent it back for a refund. I can not recommend the Defender Series to anyone. It is very disappointing that Weather Guard - a name synonymous with quality - would sell something that isn't even as good as most of the less expensive boxes I have looked at.

Rated 3 out of 5 by from A little disappointed..... I just purchased (2) of these boxes, and I expected a little better craftsmanship for the amount of money I spent on these. While the box looks good and the installation was easy, the welds along on the seams are terrible! They do look weathertight, but the corners are a glob of material and the seams are inconsistent and uneven. From a distance you wouldn't notice, but standing next to the boxes it's hard not to see what looks like a high schooler in his autobody shop class did these welds. I do like the closures and the overall appearance, I just was surprised at the quality of the construction.
