masterfit 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 Textured Finish

masterfit cargo box

The MasterFit has 15.5 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

masterfit cargo box opening

The 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 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 2 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.

Looks great, works perfectly. Always good service and prices from etrailer! Been a customer for over 20 years.
by:
As I needed something quickly and there are all sorts of supply chain issues with manufacturers, Teresa, the sales person at etrailer, did an excellent job on the phone helping me go through the inventory to find something that was both the right fit and would be available relatively soon. I very much appreciated having a capable person (as opposed to useless bots) to communicate with over the phone. It arrived in good condition and especially considering that it's the lower-priced spread (as opposed to Thule) it fits properly and is easy for one person to maneuver. I've bought a number of items from etrailer over the years and appreciate the high level of service.
by:
Easy on and off. Locks easily. Key remains in key hole when unlocked. Looks great and not too big so it's easy to handle.

Flawlessly! I highly recommend Rhino-Rack. 5 out of 5 stars!

by:
I received this cargo box yesterday and it will easily store 2 large suitcases, a bag of dog food and other items for our long trips. The attachment clamps makes it easy to install and remove from the cross bars on the car.
by:
Shipping was faster than anticipated. Product is excellent so far and glad I went with it over higher prices brands. Good customer support. Will shop here again.
by:
This has worked great on our 2019 RAV4. It holds a lot, been water-tight through all kinds of weather. The two-sided opening is extremely convenient when dealing with getting odd-shaped items in and out. The only down side is the hit on our gas mileage, but that's to be expected with anything you add to the roof. We definitely recommend!
by:
the product came quickly and boxed up on a pallet. Simple to use and simple to install on the car. Less than 10 minutes to take about of box and put on top of Toyota Highlander and tighten down. fits perfect, easy to open and close. have not used it on out trip yet, so i will updated my review when i do.
by:
Looks great. Shipping process was easy and it was delivered with extreme care. Looking forward to using it.
by:
Fits Lexus GX 460 very well to accommodate all our adventures and gear overflow.
by:
This thing is great. Can carry a ton of gear. Easy to access either side. Easy to take on and off. Definitely recommend.
by:
Box was easy to mount and I like the attachment cams. It's flimsier than I expected but I'm not shocked. I'm docking two stars for a misleading description. First, the description states the box has 6 internal anchor points but my box only has 4 - 2 in the front and 2 in the rear. Second, my box came with the two sides keyed differently. I can't think of a good reason to do this so I'm chalking it up to poor quality control. I kind of wish I had just spent more on a nicer brand.
by:
Love the roof top box. Ordered from e trailer many times in the past abs they have the best selection and shipping times. Highly recommend the roof box and etrailer.
by:
The case looks great and the delivery person did an excellent job. Let's see how it holds up on our ski trip.
by:
Very spacious and well built. Was happy with purchase. Was the correct size for my Toyota Rav 4 2022.
by:
Great box! Easy to install by yourself and very quite even at highway speeds.

I see that you said that the products you got for your Twenty Sixteen Toyota Prius, based on the review information, didnt work out. I was wondering if you had any more details as to what was giving you trouble.

  • Comparing Rhino-Rack MasterFit Rooftop Cargo Box 15.5 Cu Ft to Yakima and Thule
    The Rhino-Rack MasterFit Rooftop Cargo Box part # RRRMFT440 is an excellent option with top of the line features like dual sided opening, locks for security, master fit clamps for a fast/easy install, and internal straps for luggage security. If you compare the Rhino-Rack MasterFit Rooftop Cargo Box to the Yakima SkyBox NX 16 Roof Cargo Box part # Y95AV and Thule Force XT L Rooftop Cargo Box part # TH6357B for example, they all have pretty much the same features but the MasterFit is much...

  • Will the Rhino-Rack Cargo Box Fit the Factory Crossbars on a 2020 Honda Odyssey?
    It should work but you will need to take a measurement to confirm. I took a look at the instructions for the factory crossbars on your 2020 Odyssey. Your crossbars don't look to be adjustable so you will want to measure the distance between them. If your crossbars are between 24-3/8" and 36-5/8" then the Rhino-Rack MasterFit Rooftop Cargo Box item # RRRMFT440 will work with your van. Cargo boxes are not speed rated but these are all aerodynamic so you won't have any issues going highway...

  • How to Carry Skis and Snowboards on a 2011 Honda CR-V
    We have some excellent options for your 2011 Honda CR-V that will allow you to carry both skis and snowboards. The majority of these options are first going to require that you have a roof rack installed. For a roof rack, I recommend like the Rhino-Rack RVP Roof Rack part # RRRVP15 because it has a sleek look and installs using fixed mounting points so you don't have to worry about door clips. It also has aero shaped cross bars which are less noisy. Then in order to attach your skis...

  • Does Rhino Rack MasterFit Cargo Box Fit on Rhino Rack Aero Bar Rack for Camper Shells
    The Rhino Rack MasterFit Rooftop Cargo Box # RRRMFT440 that you referenced does fit on the Rhino Rack aero bars of the Rhino-Rack Aero Bar Roof Rack for Camper Shells # Y02-490B that you referenced. The bar height dimension of 1-1/2 inch isn't correct as the bars are actually 1-3/16 inch.

  • Cargo Box to Work with Accessory Bars on Rhino-Rack 60 x 49 Pioneer Platform
    I do have a good option for you, however your existing Yakima SkyBox NX 16 # Y95AV won't be able to mount to the 48" Accessory Bars # RR43137B on the Rhino-Rack Pioneer Platform. This is because the mounting clamps on the Yakima Box, which are spaced apart by 21 inches (side to side), won't line up to gaps in the Pioneer Platform. This means they won't be able to access the underside of the Accessory Bars for proper attachment. The Accessory Bars are primarily designed to work with accessories...
