Product Details

Swing Case by UnderCover®. If you often haul bulky items and there's no room for a toolbox in your truck bed, this swing box is the solution you've been looking for. The unique design allows the box to go over your wheel well, so when it's locked in place, it's out of the way and you can use the whole truck bed. Made of super-durable ABS plastic, the piece will protect your tools from the elements and prying eyes.



The secure, versatile, twist lock allows you to open your Swing Case with or without a key.

Provides easy access by swinging out over the tailgate...No reaching!

Your truck is all about hauling. An ATV, a dirt-bike, lumber, furniture – there is nothing your truck wouldn't be able to transport. The only bad thing is that when you need to carry bulky cargo, there's no place left for your toolbox. But then again, you want to have all those tools at hand. The UnderCover Swing Case was engineered to address your needs. This is a swinging, removable toolbox designed to tack along the sidewall of the truck bed and contoured to go over the wheel well. The ergonomic design means that the box doesn't take up the space you need to haul your cargo, and at the same time, it gives you additional 1.5 cubic feet of storage space for your flashlight, jumper cables, emergency supplies, towing equipment, sporting goods, and whatever else you might need.

The Swing Box is made of strong ABS composite and can hold up to 75 lbs of tools and gear. It is built from the same material UnderCover uses to manufacture its tonneau covers, which means the box is 100% ready to stand up to the toughest challenges. And unlike aluminum, ABS will never rust or corrode. The unit comes with two trays you can use to store smaller items like screwdrivers, pliers, etc. Another advantage is that one of the trays pops in and out so you can access items below. To make sure not a single would-be-thief will be able to reach your tools, the box has a latch mechanism that can be securely locked with or without a key. And thanks to the rubber seal that goes all the way around on the inside of the lid, the box will easily protect your tools from water and elements. You can even take this thing through the car wash – not a single drop will make its way inside the unit.

The Swing Case comes with the vehicle-specific mounting bracket that is secured with 6 self-tapping screws. Once the bracket is in place, you're actually ready to go. For you to get easy access to your tools, the box sits on the pivot joints that allow the unit to swing out 180° right over the lowered tailgate. The Swing Case won't interfere with the plywood or sheet materials that you haul as there are 2 inches of over-the-bed clearance. The company uses polymer bushings on the pivot joints, which allows the case to sit down and pivot on it without rubbing against the metal, so it doesn't rust and doesn't start squeaking. When you don't need the box, you can lock it into position with built-in quick-release pins, and should you need to take your Swing Box with you, you can lift the box out and you're ready to go. To make sure no one else will be able to carry the box away, it comes with a padlock loop.

Driver Side Swing Case
Product looks good and has plenty of space. But when bolted into place it blocks access to panels on my Tacoma so it needs to be engineered differently.

Very Handy.
This is great. Have been wanting to get this for awhile to clear up room in my cab. I have speakers underneath the back seat so this was very handy to put my straps, flares, cargo net and other handy things to have. paired with the tonneau cover and locking tailgate it's great.

Well Built!
Very simple to install. Took 10 minutes max, and part of that was searching for the right size socket in my tool bag :) I used my drill to get the self drilling screws started because I have a spray in bed liner but after that they went in no problem with hand tools as it suggests. Maybe I didn't read the description but I was a little put off by the fact that the bolts didn't line up with existing holes and I had to drill into the bed of my truck. Now if I get a new truck I have to leave the boxes with the truck or explain extra holes. They do hold a lot and is very easy to use.

Easy As It Gets!
Product is solid for being a plastic box. Install took no time at all. Holds everything I hoped it would. Only tricky part was finding a lock to fit it. Go with a puck style lock. Biggest and strongest lock I could find and get it to fit.

First Swing Box
Product looks good and was easy to install. Looking at getting second box for the passenger side. Box is a standard size. For my F-150, it could be taller and still fit under a cover. Also could be longer as it is a few inches short of wheel well.

Great Storage
Installation was relatively easy. Great for storage of items like jumper cables, minor repair tools, etc. (Now nothing under my rear seat). Like it's low profile so not seen from distance.

Works For Some, But Not Me!
This product was received from "CARiD" in record time, item(s) was/were well packaged and contained all of the necessary parts for installation. I did not complete the install the Swing Case Boxes (one for each side of the bed) for a couple of reasons: although the mounting system appears to be vehicle specific, the boxes themselves are not. It appears that the boxes are generic, in order to fit a wide variety of truck beds. Because of this, the swing cases do not properly fit the fender wells of my F-150. I was not at all happy with the appearance, the fit and finish of the installed cases. I completely understand the concept and reasoning of manufacturing generic boxes, however I choose not to install an fitting "anything" in my vehicle. Many will not care, as the cases appear to be sturdy and functional. My hat is off to "CARiD" for their quick assistance in processing my return and refund from "UnderCover".
