Cargo boxes, bags, and baskets are great for transporting gear on your vehicle's roof. A cargo box has the added benefits of an aerodynamic shape that reduces drag and wind noise, a hard shell to protect your gear, and a higher degree of weather resistance. And you can latch and lock a cargo box for added protection against theft.

Aerodynamic Cargo Box with Gloss Black Finish

Profile18B case

With 18 cu ft of space, the Malone Profile18B has enough room for sports equipment, camping gear, or luggage for 3 to 4 people. The aerodynamic design helps reduce wind noise and drag. The locking lid opens from the passenger or driver side, and it's designed to provide clearance when you open your rear hatch. Quick-attach clamps accommodate most crossbar styles and spreads so you can install the box in minutes without tools. And the durable yet lightweight ABS plastic construction helps to prevent warping, denting, or cracking.

Sturdy, Dual-Side-Opening Lid

duel side open

The Profile18B lid opens from both sides for easy access to your cargo. This means your gear is always close at hand whether you mount the box closer to the driver or passenger side. The extra-stiff lid helps reduce road noise and vibration, and it guards against dents and scratches. Built-in gas strut hinges make it easier to open and close the lid, and also help to keep the lid open while loading and unloading.

Built-In Lock

lock key

The box includes a built-in lock on both sides to secure your gear. The locks also deter theft of the box itself because it denies access to the mounting hardware. The key can only be removed once it is in the locked position, ensuring the box is securely locked and safe for transportation. 3 locking points on both sides keep the lid secure when locked.

Universal Clamp-On Mounting Hardware

Profile18B Mounting Clamps

The Profile18B installs with inward-facing quick-attach mounting clamps. These clamps fit most crossbar styles, and they are inserted into the slots along the floor of the box to accommodate different crossbar spreads. To adjust a clamp, loosen the knobs and move the clamp to the desired location. Then tighten the knobs down to close the clamp around your crossbar.

I’m ultra-pleased with my Malone Profile18b cargo box! I scoured the internet researching these things. I think I looked at every large capacity model around 18 cu ft for my Nissan Armada. There’s lots of good ones out there to choose from. I almost bought a Thule Motion XT, but I decided to go with this Malone cargo box because it had the specs I was looking for at a much better price (18 cu ft for under $xx.xx!). After examining it closely, it seems to be fantastic quality, fit and finish it great, and functions perfectly. It opens and locks from both sides—and new for this year, it has an awesome new 1-click dial attach system that installs and removes easily and holds strong. Also, It’s one of the BEST LOOKING rooftop cargo boxes out there. The Italian shape and glossy black finish looks very high-end. For the money, you can’t beat this box. If you’re considering a rooftop cargo box, don’t hesitate on getting this Malone.

- MPG911

Reviewing this after 18 months or so because in that time I have NEVER seen another one of these on the road, despite living in the roof box capital of the world (Denver) and I think it looks better than the majority of boxes I see, save the newer Thules. The price has gone up since I purchased, but I still think it's good value. Great roof box option at a fraction of the price of Thule/Yakima, plus it looks sleek and the shiny finish looks great. I frequently use this for cargo storage / skis and snowboards across 3 different vehicles and bars (Jeep Renegade on Yakima Aerobars, VW Golf on OEM square bars, Subaru Forester on OEM bars) and it's great. Easy to take on and off and always feels secure. I've fit ski's up to 190cm in it carefully at an angle - my buddy's 196cm skis wouldn't fit without bending. I will say that, as with probably any other roof box, you need to be careful of the locks fully engaging and not being blocked. I've had issues getting the box re-opened once locked if something inside is pushed up against one of the 3 lock points.

  • Quality Comparison Between Thule XT Roof Cargo Boxes and Malone Cargo Boxes
    When it comes to overall quality, design, and ease of use you really can't beat Thule cargo boxes like the Motion XT part # TH629806 or the Force XT part # TH6358B. Thule has been making cargo boxes for a very long time and over the years they've kept raising the bar for how nice the boxes can be. They are expensive for sure, but they are the best you can get. The Malone Profile18B Rooftop Cargo Box # MPG911 is a solid value for a solid box, but at this point you already spending quite...

  • Recommended Waterproof Storage for Boat Roof
    I have a solution for you, but there are a number of different reasons that a cargo box is not going to work on that roof. To start, all of the boxes that would allow you to have 40" space between the cross bars are going to be extremely long; the Yakima SkyBox 21 # Y07337 will accommodate up to 42" crossbar spacing, but is 92" long and 36" wide. All of the boxes available that are short enough and narrow enough that are able to fit in that space require between roughly 24" and 35-3/8",...

    The Malone Profile18B Rooftop Cargo Box # MPG911 referenced in your question will work perfectly on your 2013 Hyundai Santa Fe factory roof rack as long as it has a crossbar spread of 24 to 36 inches. This simply refers to the distance from the center of one crossbar to the center of the other. As long as this dimension is between 24 and 36 inches the box will mount without issue to the roof rack. The width and length of the crossbars themselves will not be an issue. One other measurement...

  • Will Two 33" x 29" x 12" Boxes Fit Inside the Malone Profile18B Cargo Box
    It would be a tight fit but based on the dimensions of the Malone cargo box # MPG911 and your 33 x 29 x 12 inch boxes I believe you could get them to fit in the box. Another option is to use a roof basket, # Y07080-82, and a cargo net, # C18201. A basket will be easier to store since it won't take up as much space. A box though can be locked so there are advantages to either option.

  • What Crossbar Spread Distance Between Bars Does Malone Cargo Box MPG911 Fit
    The Malone cargo box part # MPG911 can fit on crossbar spreads of 24-36 inches like what you mentioned. This means that if you measure from crossbar center to crossbar center on your roof rack and that dimension is between 24 and 36 inches this box will fit and work well.

  • Lenght of Skis to Fit Inside Malone Profile18 Rooftop Cargo Box
    I reached out to my contacat at Malone and the Profile 18 cargo box, part # MPG911, does measure 78-3/4 inches for an exterior length so it only holds skis up to 195 cm. In some cases it may be possible to get 205 cm skis in the box if they can be angled but this wouldn't leave much room for any other cargo.

    We haven't had the chance to test fit the Malone Profile18B, part # MPG911, on a 2017 Jeep Renegade as of yet but it's designed to fit most factory roof racks so that shouldn't be an issue for you. The only issue you may run into is whether you can open the rear hatch without making contact with the roof box.
