Save your money and do not buy this product, it's poorly manufactured to say the least. 1), the plastic gauge is way to thin making the final product to flimsy. 2) while the order information asked me for make, model and year of vehicle it did not match factory rail specifications. The factory roof rack system for Honda CRV is not adjustable and the 22 inch spread identified for product does not work for Honda installed roof rack systems. 3) lastly, the hinge design on this unit is poorly designed and will not align without modifications to bend the tabs so that they properly align with the slots.

Once again, do not waste your money on this product.

This rooftop cargo box can accomodate up to a 30 inch spread on some crossbars, but it would involve drilling to the custom measurements of your CR-V crossbar spread.



by:

The roof top box is definitely big enough for my all my family's gear, planning a road trip out West that includes some camping along the way.

The plastic was a bit flimsier than I had expected and I was NOT impressed with the PLASTIC clamps around the side. I'm not too worried of the lid flying off if a clamp or two breaks - the front of the box locks and there is a pin in the rear hinge - however, I'm packing extra rope just in case. It also appears that the rivets holding the rails and lock to the container are also made of plastic.

I do a lot of camping, I'll likely update my review after putting it through a few runs.



by:

I am not completely satisfied with this product, although it holds things ok. Made of plastic that is very flimsy/flexible. Would be better if it was rigid plastic. Also find the support holders are a bit difficult to put onto the little pegs (can't really see them do to being inside). Purchased for our make and model and still had some difficulty installing. Was not pleasant and I usually enjoy doing projects.



by:

I have a 1 star because I am very disappointed in the quality . The plastic
Cover is badly warped out of the box making it very difficult to close. For the price of this product I am dissatisfied with the quality.



by:

Put it together in just a few minutes. Very easy. Haven't actually mounted it to the car yet. In my case, I think side opening would be preferred as the Traverse is very tall and will require a small step ladder to reach the lock.

  • What is the Widest Cargo Box that Will Fit Rola Roof Rack 59833 on a 2013 Mazda 3
    The spacing of the feet of cargo boxes will be narrower than the overall width of the cargo box. So basically what that means is you could use any cargo box so long as it has attachments that are compatible with the Rola crossbar dimensions and spread (spread being the center to center distance from one bar to the other). I believe the widest box we have is around 38-1/3 inches # TRX34FR.

  • Roof Rack for 2018 Buick Encore to Use Trunx Rooftop Cargo Box
    A roof rack does need to be purchased separately for your 2018 Buick Encore to install the Trunx Rooftop Cargo Box # TRX34FR. The roof rack used in the video is a Rhino-Rack and is truly the best option for a roof rack for your '18 Encore because it is the best value. The Rhino-Rack is the most budget-friendly roof rack that fits your Encore but is still a very high quality so I strongly recommend going this route. The rack will mount to the flush rails on your Buick and is made up of...

  • Will the Thule Sidekick Cargo Box Fit a 2015 Subaru Outback without Hatch Interference
    For the Thule Sidekick Roof Mounted Cargo Carrier Box - U-Bolt Mounts - 8 Cubic Feet Item # TH78GC there will need to be at least 51-7/8 inches from the center of the front crossbar to the line where the roof and hatch meet to avoid hatch interference on your 2015 Subaru Outback. I do have another option for you though. You can use the Trunx Rooftop Cargo Box - 18 cu ft - Black # TRX34FR which requires just 36 inches clearance. Plus it costs less and has more cargo space than the Sidekick!...

  • Will the Yakima SkyBox 21 Fit My HD Bars on Our Trailer?
    I have a great cargo box solution for you. Without knowing the exact model or dimensions of your HD bars on your trailer, the Yakima SkyBox 21 # Y07337 will fit if the crossbars do not exceed 3-1/2 inches wide x 1-11/16 inches tall. In order to confirm if they fit or not, I recommend measuring your crossbars. If you discover that the SkyBox 21 will not fit your bars, there is unfortunately no HD adapter that will allow you to fit the clamps around the crossbars. The only other rooftop...

  • Will SportRack SkyLine XL Cargo Box Fit 2018 Chrysler Pacifica With Factory Crossbars
    We do have a cargo box that will work for your 2018 Chrysler Pacifica with the factory roof rack, but according to my research, the SportRack SkyLine XL Cargo Box will not fit. A cargo box at a similar price point which I can confirm will fit is the Trunx Rooftop Cargo Box # TRX34FR which will fit crossbar spreads from 22" to 31" but will require drilling new holes in the bottom of the box to get the U-bolts to mount to your Pacifia's crossbar spread. Like the SkyLine, the Trunx can handle...

  • What Roof Cargo Box that Can Fit Crossbar Spread of 30-1/4 Inches
    Since there isn't a safe way to modify or adapt the Sportrack roof box you have to fit the wider crossbar spread you have the best solution we have would be a new cargo box that is compatible with that spread. The most similar solution we have would be the Trunx Rooftop Cargo Box - 18 cu ft - Black # TRX34FR which can have it's mounting holes redrilled to fit your crossbar spread of 30-1/4 inches. This box also has the same cubic footage as the SportRack SR7095.

  • Recommended Cargo Box for 2019 Toyota RAV4 That Doesnt Obstruct Roof Antenna
    In order to use the Thule Motion XT # TH629706 on your 2019 Toyota RAV4 you're going to need 47-1/2" from the center of your front crossbar to the crease where the roof and the hatch meet. However, it's going to be substantially less than that when it comes to the antenna, so using a long box like this likely isn't going to be the best solution because you're likely going to see some reception issues if it's covered. I recommend considering the Trunx Rooftop Cargo Box # TRX34FR, since...

  • Crossbar Spread Required for Trunx Rooftop Cargo Box
    I'm certainly sorry to hear about the cargo bag issue you had going through a snow storm. Cargo bags are really handy and easy to manage but weather can be an issue so you are smart to go with a cargo box. The Trunx Rooftop Cargo Box # TRX34FR you referenced uses U-bolts that will work on crossbar spreads from 22 inches to 31 inches and the spread of the SportRack Roof Rack # SR1010 on your Ford Fusion is going to be in that range so it is definitely going to work. The cargo box will...

  • Trunx Rooftop Cargo Box that Can Fit Cargo that Measures 39x12x11.5

Unfortunately, we do not currently carry crossbars that are long enough that are recommended for your 2020 Toyota 4Runner that will let you attach the Trunx Rooftop Cargo Box - 18 cu ft - Black # TRX34FR along with your 33-1/2 inch long x 49 inch wide cargo basket. Also, we currently do not carry any hard cargo boxes that will allow you to safely attach it to your basket.

  • Roof Cargo Box that Can Fit 2021 Toyota Sienna with OEM Crossbars
    The Trunx roof top cargo box part # TRX34FR can fit the crossbars of your 2021 Toyota Sienna but you would need to drill new holes in the box unless your crossbars can be placed right at 22 inches. Basically any roof cargo box will fit your vehicle but if you wanted something a little nicer yet in same price range the Malone Profile18s part # MPG910 would be a really great option. It has a sleaker design, opens from the side, and has easier to use mounting hardware as well.

  • Can I Drill Holes in the Trunx # TRX34FR to Accomodate a 38.5 Inch Bar Spread?
    I have cargo solution for you. While it may technically work to drill holes for the mounting hardware of the Trunx Cargo Carrier # TRX34FR, the manufacturer does not recommend drilling holes to accommodate a crossbar spread over 31 inches. Since we do not know the exact Yakima crossbars you have on your roof rack, the Trunx carrier will clamp around the bars as long as they do not exceed 3-3/4" wide x 1-3/16" tall. I recommend measuring the height and width of your crossbars to make sure...

  • Rooftop Cargo Box to Replace Yakima Space Booster for Which Parts Are Not Available
    Thank you for the photo of your 1980's vintage Yakima Space Booster rooftop cargo box. I do understand and admire your interest in keeping that old box in use. I myself am "that guy" too. However, my contact at Yakima said they have not supported this box with replacement parts for quite a long time, due to its age. Available replacement parts for Yakima boxes can be seen on the linked page; most of these are for their newer products. Since your box requires lid supports that are no longer...

  • Trailer Hitch for a 2006 Mercedes-Benz CLK-350 Coupe
    I would love to help but they do not make a trailer hitch for your 2006 Mercedes-Benz CLK-350 coupe, just the convertible. I would also be skeptical that your vehicle is rated to tow a trailer. However, if you can tell me what you will be using the trailer hitch for I would be glad to see if we have any alternative options for you. For example, if you need more space for cargo then you can install a roof rack like the Rhino-Rack Aero Bar Crossbar System part # RRVA118B-2, part # RRRLKVA,...

  • How to Fit the SportRack Roof Rack # SR1010 on a 2019 Kia Niro with Bare Roof
    While we do have a great fitment for you, I confirmed with SportRack that the SportRack Semi-Custom Roof Rack # SR1010 does not fit a 2019 Kia Niro PHEV with a bare roof. This is because the # SR1010 was designed to fit certain styles of roofs. The shape of your particular roof style and doors cannot accommodate the shape of the door-jamb clips and feet. With that being said, the best and only guaranteed fitment we have with your bare roof is the SeaSucker Monkey Bars # 298-SX6000B. Since...

  • Can I Drill Holes into the Trunx # TRX34FR with a Crossbar Spread Longer than 31 Inches?
    I have a great rooftop box option for you, but we do not recommend drilling into the Trunx Cargo Box - 18 Cu Ft. # TRX34FR with a 32-1/2 bar spread. This is because the maximum allowed crossbar spread for the # TRX34FR with drilling is 31 inches apart. It is always strongly recommended not to exceed any limits put in place by the manufacturer because doing so can not only cause damage and void warrantees; it can also be dangerous. On top of that, we have not installed the # TRX34FR with...

  • Will Trunx 18 cu ft Rooftop Cargo Box Fit OEM Roof Rack on 2016 Subaru Outback Wagon
    Yes, since the Trunx Rooftop Cargo Box # TRX34FR can fit up to a 31" crossbar spread (with drilling) you will be able to fit this box on your 2016 Subaru Outback Wagon. Crossbar spread is the distance from one point on a crossbar to the same point on the other crossbar so your spread is 30.25". Attached is a review video for you to check out.

  • Will the SportRack SkyLine Cargo Box Fit on Factory Crossbars of a 2018 Kia Sorento
    Yes. The Trunx Rooftop Cargo Box - 18 cu ft - Black # TRX34FR is designed to fit on most aftermarket and factory roof rack crossbars, so as long as your 2018 Kia Sorento's factory bars aren't wider than 3-3/4" this box will fit without any issues. Most crossbars aren't that wide and I have yet to encounter a factory crossbar that this box hasn't fit on, so the Trunx cargo box will do a great job.
