zenith cargo box diagram

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 High Gloss Finish

zenith cargo box

The Zenith MasterFit has 14 cu ft of space for sports equipment, camping gear, or large luggage for up to 3 people. The aerodynamic, low-profile design helps reduce wind noise and drag. The locking lid opens from both sides, and it's designed to provide clearance when you open your rear hatch. Sliding 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

zenith cargo box opening

The Zenith MasterFit lid opens from both sides for easy access to your cargo. This ensures your gear is always close at hand whether you mount the box in the center of your roof or closer to the driver's or passenger's side.


Built-In Security

Rhino Rack Master Fit Lock

There is a lock on each side of the box. These locks prevent you from removing the keys if the box is not properly closed and locked. This eliminates the possibility of the box opening as you travel down the road. And because the buttons that lock the clamps to your crossbars are inside the box, locking the mounted box prevents would-be thieves from removing the box from your roof.


MasterFit Mounting System

Rhino Rack Clamp

The Zenith MasterFit installs with easy-to-use clamps. These clamps fit most crossbar styles, and they slide along tracks in the floor of the box to accommodate different crossbar spreads. Large, easy-to-grab knobs with built-in locking buttons make adjustment simple. Press the red button to open the clamp, slide it into place over your crossbar, then turn the knob to secure it in place. The knob clicks when it's tight so you won't overtighten and damage your crossbars. Press the red button again to secure the clamp in place.


Cargo Tie-Down Anchors

Rhino Rack Luggage Strap

It includes 3 tie-down straps to secure your gear to 6 internal anchor points. These nylon straps have cam buckles so you can tighten them down to secure your luggage. Metal rails on the bottom of the box reinforce both the internal anchor points and the mounting clamp tracks.

This was a great experience from start to finish. etrailer: After placing the order, I called regarding shipping and quickly got the answer to my question. The box shipped by ground freight, and arrived almost a week before the original scheduled delivery date. The Rhino arrived perfect with protective wrap, and all the required parts. Rhino Rack: This thing is awesome. Unless you jump up into the $1000+ price point, your rooftop carrier options are limited. My two requirements were to fit my skis (181 & 183 cm) and to allow my tailgate to open fully. The Rhino delivered! Bonus that both baby strollers fit as well (Instep baby trailer and Vista Uppababy). Only a week in, but so far the Rhino box and MasterFit clamps seem solid. The ratchet/locking mechanism on the clamps is just ok, you don't have to twist too hard to over power the lock or feel like you are stripping something internally. The hinges are beefy, but don't take up a ton of storage space. It opens from both sides, and you can't remove the key unless it's locked, which is nice for those of us that don't enjoy picking up our stuff on the highway. Also, if you're like me and spent way too much time on mr-box.com, you'll be pleased to know that this thing doesn't look lame. It's pretty sleek, somewhat low profile, with a touch of Euro. It's not too wide, even on the narrow rails of the A4 Allroad there's extra bar space. I could probably squeeze an upright kayak rack, small ski pinchers, or for the ten of us in the world that own RoadShowers...the RoadShower 4 fits no problem. I definitely recommend a Rhino from etrailer.

Review from a similar Master-Fit in Roof Box


I bought this cargo carrier for my family's epic road trip last year through Utah's Mighty Five National Parks which included time at the Grand Canyon, Mesa Verde, the Four Corners, and Monument Valley. For 12 days over 4000 miles we used this carrier to haul our adventure gear of backpacks, trekking poles, shoes, and extra supplies. We drove through Kansas thunderstorms and dusty Arizona desert roads undergoing construction. This carrier never failed and kept our gear out of the way and secure. It is light weight and easy to install by one person. It has very little wind noise for being a behemoth strapped to the roof. I noticed about 4 mpg loss in fuel economy but that is to be expected. I love that you can access your gear from either side and that you can't pull the key out while it's open. That's a great reminder to close it which also locks it shut. Overall, a great product at a great price. Delivery was by lift gate truck on a pallet which is ironic given how light weight it is. We collected National Park stickers everywhere we went to attach onto the carrier. It's a fun reminder of all the wonderful places we've been together as a family.


Comments
After using this carrier on multiple road trips and vacations over the last two years it still functions flawlessly. Its simple to install and remove by one competent adult although having two people is easier just due to its size. When not in use I store it in my garage which should keep it in good shape for many more years to come.

Review from a similar Master-Fit in Roof Box


Used this with Rhino racks on top of 2013 Hyundai santé fe. Quick and easy to install. Light enough to install myself without help. Only issue was tight spacing of the lock downs to the roof racks. With the roof racks as close together as possible (fore-aft) using the factory holes on the car roof supports this barely was able to lock onto them. However, I got it installed but it was very very close to not fitting, as could have used larger spacing on the cargo carrier.

The Rhino Rack is fantastic! It is the best carrier I have ever owned. Durable, Water Tight and locks securely to the overhead racks on my truck. I would recommend etrailer.com and the Rhino Rack to anyone.

Review from a similar Master-Fit in Roof Box


We've used for two snowboarding trips. Selling point for me was access from either side. This is a must-have feature because trying to get something from the far side on a roof-mounted container is near impossible unless you're a pro basketball player. We were able to store three snowboards with bindings, snowboard boots, winter clothes, boot dryer, and other items in the carrier without any problems. This definitely made our 12-hr (one-way) snowboarding trips more enjoyable with the freed-up space in the vehicle.

Trying to figure out where everything is going to fit and still have room for all of the family or friends on your next excursion? What about items purchased or found while on your trip? This cargo carrier has been one of best accessories we have ever purchased for our Toyota Rav4. It accommodated suit cases, clothing, shoes and other items you would take on a journey. Going swimming with the kids, you now have a place for all things wet. Also, installation and removal are a breeze. When it comes to traveling, the Rhino Cargo Carrier will be a fixture on our rig.

Review from a similar Master-Fit in Roof Box


Overall I'm extremely pleased with the product. It has surpassed my expectations. Allowing me the freedom to free up much needed space in my wife 2009 RAV4. We have driven to Wisconsin, Tennessee, and Georgia for family vacations. My only complaint is that it is a little difficult to lock and secure when the container is filled with gear/clothing. Great product for the price, extremely satisfied!!!

Review from a similar Master-Fit in Roof Box


It's a decent size but the latch mechanism is made of plastic and doesn't lock into position well, especially considering we've only used it a few times. Etrailer.com is great, it's the product itself that gets 2 stars.

    As far as the compatibility of the Rhino-Rack Zenith MasterFit Rooftop Cargo Box - 14 cu ft - High Gloss Black # RRRMFZ66, it will allow you to fully open your rear hatch on your 2019 Toyota RAV-4 when mounted.

  • Dimensions of Rhino-Rack Zenith MasterFit Rooftop Cargo Box Where it Touches the Roof Rack
    The 76" long x 32" wide x 14" tall dimensions that you referenced are the overall dimensions of the Rhino-Rack Zenith MasterFit Rooftop Cargo Box # RRRMFZ66. When it comes to the slides for the mounting hardware on the Zenith MasterFit the overall dimensions are 16-1/2" x 43-1/2". The lower part of the box that will sit about level with your crossbars is 70" long and then it narrows from 29-1/2" to 27" as far as width goes. I've added some photos to help demonstrate this.

  • Internal Space for Skis/Snowboards with the Rhino-Rack Zenith MasterFit Cargo Box
    I pulled the Rhino-Rack Zenith MasterFit # RRRMFZ66 from the warehouse and found that there is about 12-1/2" between the mounting knobs and about 14-1/2" between the tracks they sit on. Lengthwise there is about 68-3/4" between the hinges. You may need to get creative with how you load them to avoid damage but those are the dimensions you have without them touching anything else inside the box.

    We can definitely find a rooftop cargo box that will work with your 2019 Toyota RAV4. You are looking for a low profile cargo box. Please keep in mind that the lower in profile a box gets, the longer it becomes to keep the same volume.

    As long as the factory crossbars on your 2016 Honda Pilot are not taller than 1-3/8" and wider than 3-9/16" then the Rhino Rack Zenith MasterFit Cargo Box # RRRMFZ66 will fit on the roof without issue. You'll want to make sure that the distance between the front crossbar and the line where the roof meets the rear hatch is greater than 49-1/4" in order to confirm that you can open the rear hatch when the box is installed. As long as your 2016 Pilot meets these two criteria you'll have no...

  • Rooftop Cargo Box For 2018 Toyota Highlander With Factory Roof Rack & Sunroof
    You can certainly use a rooftop cargo box on your 2018 Toyota Highlander with a factory roof rack and sunroof, and if you leave the sunroof closed, there won't be any issues. That said, opening the sunroof could be a different story; while it's highly unlikely there will be interference with a clamp-on cargo box, the clamps will extend past your crossbars an inch or so. I assume you have the panoramic sunroof on your '18 Highlander, and from what I know of that sunroof, it does jut...

  • Will Yakima SkyBox 21 Fit on Rhino-Rack Heavy-Duty Roof Rack Crossbars
    The max dimensions for a crossbar that the Yakima SkyBox 21 # Y07337 can accommodate is 3-1/2" x 1-11/16". The Rhino-Rack Heavy-Duty Roof Rack Crossbars # RB1250B-2 are a little too tall for that so if you want to stick with Rhino-Rack you need the Vortex crossbars like part # RRVA137B-2.

We actually have reached out to Rhino-Rack about cargo boxes fitting with the Pioneer rack and they have said that all of their cargo boxes are compatible with the rail spacing on the Pioneer.

  • Roof Rack and Cargo Box Recommendation for a 2019 Kia Sportage
    Yes, for your 2019 Kia Sportage with raised side rails I recommend using the Rhino-Rack Vortex Aero Crossbar System which is composed of part # RRVA126B-2 and part # RRSX023. This system has aero shaped crossbars which will reduce both wind noise/resistance and it comes with locks for security. It has the same quality and dependability as other major roof rack manufacturers such as Thule and Yakima but without the added price. I have attached a photo of the crossbars installed as well as...
