84 x 36 x 16-1/2. Free up space inside your vehicle and carry gear on your roof with this cargo box. NX nano-texture finish is scratch-resistant. Dual-opening lid provides easy access from either side of your vehicle. Clamps mount to most crossbars.

Specs:
The SkyBox NX lid opens from both sides so you can easily access cargo from the driver's side or passenger's side of your vehicle. If you are parked on a busy street, in a tight parking lot, or even next to a campground picnic table, you have the option of opening the lid from the side of the vehicle that works best for you.
The fortified lid has an easy-access edge and spring-loaded hinges that allow for smooth, one-handed operation. Also, since the lid is extra-stiff, it helps reduce road noise and vibration. Finally, it has a nano-texture finish that helps guard against dings and scratches when you're on the road or when the box is in storage.
The SkyBox has security latches on both sides to ensure the lid is completely closed and locked. This system prevents you from removing the key from the lock unless all 3 internal latches are engaged. That way, you are prevented from removing the key and driving off with an unlocked box. Also, the SKS lock core can be swapped out to make all your Yakima gear keyed alike.
The SkyBox installs with mounting clamps that slide along tracks in the floor of the box. These clamps fit most crossbar styles and they adjust for different crossbar spreads. To adjust the clamps, loosen the knobs with the included torque tool and slide them to the desired location. Then, tighten the knobs and close the clamps around your crossbars.

Ratings & Reviews
We are very happy to report this Cargo Box has held up to all the reviews, we read, before purchasing. Sarah was very helpful in assisting us to which size would work best for us. We would highly recommend this company and this product! Great product and excellent customer service & experience.
Great product. Very happy with my purchase. Owned the largest box available from another manufacturer for years and the problems with attachment and locking of the older box are all remedied by this Yakima iteration. Ease of use with regard to attachment to vehicle and opening and closing is simple and straightforward with little room for error by design.
1. The item arrived in acceptable condition and with all items described.
2. The item was in the condition described at time of purchase.
3. The item I purchased was sold at a very fair price, I believe:
4. The shipping for the item was fast and I could follow every step of the process.
5. The people who were involved in making sure my item arrived, from the sales associate online to the freight driver, were friendly.
I wish I could order everything off of etrailer, it's the best. Great/detailed customer service, and the shipping companies they work with are top-notch. This place is fantastic, and if you're thinking about buying through etrailer, this is your sign to do it: I am very satisfied with my purchase.
This box has served us well. It was subjected to a few heavy rainstorms and stayed dry. Fairly easy to mount by myself. Definately need to keep after it for UV protection as it will fade. Was a good purchase.
Arrived Friday for Memorial Day weekend. Was looking forward to using it for a camping trip but, could not get either side to unlock. Tried both keys numerous times. No luck. Have to wait until Tuesday to call customer service. Not Happy.
Safely delivered without damage. Lauren at etrailer.com made this a very smooth transaction! Thank you!
I hate writing ratings, BUT, this product is great. The finish on the product is very impressive.
Delivery….the driver called several hours before delivery to give me an estimated delivery time, kept me posted and was wonderful. Etrailer products are great.
Highly recommend
Well designed, love it...
Installed Yakima SkyBox NX 18 as advertised. Fit vehicle (Outback with factory bars) perfectly. Careful not to open the clamps to much during first install. You might scratch or dent your roof. Would be good if 3/16 hex wrench was included for horizontal adjustment of bar clamps. Will see it the hinges and fasteners stand the test of time, but it looks like Yakima has a well thought out product.
I consulted with Josh to confirm my order and discuss some of the details on fitment. He answered them all! Skybox NX 18 arrived on time and in perfect condition. 2023 Hyundia Santa Fe Hybrid Limited.

Exactly as advertised. Fitment was great with coaching from your customer service. Thanks
Excellent box and installation is a bre eze!
The cargo box arrived quicker than expected and was in excellent condition.
Install went well. Fit looks perfect.
Awesome service from E-Trailer. Super fast shipping and great communication regarding the delivery from the freight shipping company. Cargo box is well built and functions flawlessly. Nice product and nice fit on top of Infiniti QX80. Thanks E-Trailer!
This is my first box. I have been using bags previously. Man I wish I upgraded sooner. This was a breeze to install, even with the aftermarket Prinsu roof rack. Just had to slide some bars around, and I got a really nice low profile install.
Fit perfectly, no wind noise, didn't even know it was on the roof. No loss of mpg. Good quality easy to install.

We are thrilled with our purchase! Ordering from etrailer was a pleasure and saved us over $160 in shipping costs. The packaging provided excellent protection and there was not a mark on our roof box. The Yakima SkyBox NX 18 is a welcome addition to our 2023 Jeep Grand Cherokee L. The fit on our vehicle was perfect and the 18 cu ft. capacity of the box is impressive. We were able to fit a 3 piece luggage set (Full Size suitcase, Carry On, and small roller bag) as well as a jogging stroller for our 3 year old. Highly Recommend A++
Service and delivery 5 stars. Product 4. I like it, it will work just fine, it was very easy to mount on my wife's outback. For the price it's not that much of an upgrade over the overseas made ones but I am willing to pay more for an American made product from a very reputable company with what I hear great customer service. I wish it opened a little easier, you either need to give it a solid push or assist it up slowly. I've had other boxes that opened much better but they were half the size. Decent product but it's a lot of money for plastic.
Great customer service. Great box, very roomy and sturdy. Arrived early very nice delivery person. Was kept up to date every step. Highly recommend!
Purchased for my 2023 Honda Pilot with factory crossbars. The cargo box is an excellent value compared to other products in this size range. It can easily hold our soft luggage for a family of 5. I also find the locking mechanism and hinge design very thoughtful - I'm confident the carrier is fully closed and locked. I also like the integrated torque wrench clamps; they are very low profile and I'm confident the box isn't going anywhere. Yakima should include straps at the price point.
I had been thinking about buying this box for a long time, and when the perfect moment finally came, it did not disappoint. We needed extra space due to our move to another state, and this roof box was a lifesaver — the two of us, plus our dog, were running out of space in our SUV. The car was literally packed with a mix of furniture and personal belongings.
The box fits 4 suitcases: 2 large and 2 small, which exceeded my expectations! We had an amazing trip from the very north to the south of Florida. The box is durable, surprisingly light for its size, and easy to install. The real game changer is that it has 2 locks on both sides, so we felt at ease knowing our belongings were secure during overnight parking.
With this roof box, we will definitely start traveling more — because traveling with our pup is not an easy feat. Highly recommended, worth every penny!
