Great fitting hardware for a large asears cargo carrier on Porsche crossbars. Delivered in 4 days with timely updates. Highly recommend ETrailer!


Reasonably priced; arrived quickly; fits and works great !


I found the website extremely easy to use and when I did call customer service to verify I was ordering the correct item they were very helpful and patient with me my item was shipped quickly


I used the Rhino S280 clamps to attached two Yakima Basketcase baskets to Rhino Aero rack system


Purchased to replace lost hardware. Used on a Thule Adventure box. No modifications necessary.


Product is exactly as described, and quality appears solid upon initial inspection. Fit was accurate as well. This helped me mount a Thule box with 4 inch hole spacing onto a 2008 Mini Cooper with the factory no-drill chanel mounted roof rack. I required this style to account for the thicker aero style bars.

I would recommend using a foam tape on the metal pcs to keep from marring rack or box but not mandatory.


Used for a pep boys roof cargo carrier. Held up perfect on a 850 mile trip.


Honestly, the tray is just your basic Rhino mesh tray, so we all know the quality is going to be top notch and the product will be as advertised. That said, let me know immediately after ordering that they didn't have it in stock at their main warehouse, that they were doing everything they could to locate one for me with one of their partners, and that it would ship asap, but separately from the mounting hardware I ordered along with it. Turns out the hardware arrived right on time, whereas the tray showed up a day early. George from etrailer kept me updated via email the whole time. Amazing customer service guys! Highly recommend!


I bought this set of clamps to retrofit my Thule Adventurer for my Aeroblade bars. Thule has no fix for this problem. Rhino Racks also had no fix as the S280 clamp set had been discontinued, however they gave me the URL for and told me that they had a generous supply in inventory. I went to and found them there. The purchase was easy. I did have to call them because it was not clear how shipping (post or UPS) was handled. (I have a post box at the local post office and a different physical address, SO THIS MATTERS!). Delivery was prompt and solved my problem.


Well made parts...worked fine to secure an old Yakima box to wide cross rails.


Everything worked perfectly thank you


Fit my Subaru Aero cross-bars perfectly.
what I needed.


Arrived as expected and fit great on my Yakima Aerobars


It works perfectly.


Very happy with the low profile of this rack and the ease of the install. Seems to be heavy duty and the finish very durable but time will tell.


Product provided is as described and quality is as expected.


This item was the perfect size for my needs. I will be recommending you to all my Subaru enthusiast


Parts came quickly and really excellent customer service!!!!




Product as advertised. Quick shipping.



Fast shipping on a hard to find accessory, thanks for the great deal

  • Can the Rhino Rack Steel Mesh Roof Mount Cargo Box be Mounted to Yakima Round Crossbars
    The Rhino Rack cargo basket, # RLBN-S280, mounts to crossbars up to 3-7/8 inches in diameter, so the hardware will fit Yakima round bars. The maximum bar spread, measured center to center between the bars, cannot exceed 79 inches. The crossbars must also be at least 16 inches long. For a more secure fit to Yakima bars, you can use fit kit # MUBK. It is not required but will be a better fit to Yakima round bars. I have linked instructions for you.

I also have U-bolts...

    What type of crossbars do you have on your 2018 Toyota 4Runner TRD? If they are the Rhino-Rack Heavy-Duty Crossbars then yes, the Heavy-Duty Crossbar Fit Kit for Rhino-Rack Steel Mesh Baskets and Steel Mesh Trays part # RUBK is correct for you. However, if you have aero crossbars then you will want to use the Aero Crossbar Fit Kit for Rhino-Rack Steel Mesh Baskets and Steel Mesh Trays part # S280 or if you have square/round crossbars you will want to use the Round/Square Crossbar Fit Kit...

  • Mounting Hardware for Thule 250 box onto Volkswagen Golf Alltrack Crossbars
    The best option we have for replacement hardware for your Thule 250 box is the QM3 kit part # TH04997 which would give you mounting hardware that would fit the factory bars of your 2019 Volkswagen Golf Alltrack. You will have to modify the box to make this fit so you'll need to use your best judgment. This will be much safer that zip ties too!

  • Can Rhino-Rack Fairing be Used with Rhino-Rack Mesh Cargo Tray on 2011 Honda Odyssey
    Yes, you can use Rhino-Rack fairing # RRRF2 with the steel mesh cargo tray # RPBS-S280. You will want to first install the fairing and then install the cargo tray because there would not be a way to easily get the fairing hardware in place if the tray was in the way.

    My contact at Rage Powersports advised that they no longer have original replacement installation hardware for their Stingray roof cargo basket but this kind of product can often be safely used with alternative hardware it if fits your roof rack bars and the basket itself. It sounds like your vehicle's roof bars are about 4-inches wide. We offer a Rhino Rack install kit # S280 that will fit bars up to 3-7/8-inches wide; you'll want to carefully measure again to see if these will fit your...

  • Center to Center Spacing of the Car Top Kit U-Bolt for Older Yakima Cargo Box
    The U-Bolts that come in the Car Top Kit # CTC-18PARTS and the Rhino-Rack Kit # S280 measure 4" apart on center. It is possible to use a mounting kit like this on an older Yakima box if there isn't anything else available although you may need to drill new holes and seal the old ones with something like part # LT37467. There may be a replacement mounting kit from Yakima depending on what you have. If you can let me know the name of your Yakima cargo box and/or send me a picture of it...

  • Can Different Hardware be Used to Mount Rhino Rack Basket to Vortex Crossbars on 2016 Jeep Renegade
    I have a possible solution for you but the hardware that comes with the Rhino-Rack Xtray cargo baskets such as # RMCB02 is unique in the way it attaches to the actual basket. Each foot mounts along 2 of the basket's front to back rails so no alternate hardware will fit. But take a look at the Thule Canyon XT # TH859XT. It uses just the U-Bolts so there is more space between the bottom of the roof rack rails and the top of the vehicle roof so you should have plenty of room for your sunroof.

  • Does Rhino Rack Roof Carrier # RPBL-S280 Include Universal Hardware and Install on Thule Load Bars
    The Rhino Rack Roof Cargo Carrier, part # RPBL-S280, you have referenced does come with a universal U-bolt hardware mounting kit. Anytime you are going to haul cargo on the roof of a vehicle, you do need to find out the weight capacity of your roof. You can check the owners manual or contact the car dealer for the roof weight capacity that is allowed for your 2011 Toyota 4Runner Trail Edition.

  • Is the Rhino Rack Steel Mesh Cargo Tray Compatible with Thule Bars and Fairing
    You should have no problem installing the Rhino-Rack Steel Mesh, Roof Mounted Cargo Tray # RPBS-S280 on your Thule square cross bars that have a Thule 38 inch Fairing # TH72WV installed on them. The fairing should not give the rack an uneven look as the clips of the fairing are pretty thick. However, what you could do is install a couple Replacement Load Bar Clip for Thule Roof Rack Fairings # 8537361 on the rear cross bar as well so that the # RPBS-S280 would sit as level as possible...

  • Thule Canyon Cargo Basket and Lock Cylinders Recomendations for a 2011 Chevy Equinox
    I believe I have a solution for you. You should check out the Thule Canyon XT Roof Top Cargo Carrier # TH859XT. This is a cargo basket that I confirmed with Thule as fitting the factory crossbars of your 2011 Chevy Equinox, comes with a fairing and is capable of having lock cylinders installed as a theft deterrent. To get lock cylinders you would want Thule Lock Cylinders part # TH450400. I do not recommend the Rhino Rack Roof Mounted Cargo Tray # RPBM-S280 since there really is not way...

  • Can Accessory Carriers Mount to Rhino Rack Steel Roof Cargo Tray RRRPBS
    The Rhino Rack Steel Roof Cargo Tray RRRPBS does not have specific accessory mounts for the items you mentioned like light bars and shovel mounts but if you had such accessories that can mount on the tray's 1-inch round tubing and available space its steel construction will handle them. This tray requires a mounting kit and there are several to choose from depending on the type of roof rack bar you're using. For aero, elliptical, and most factory crossbars use kit # S280.

  • Cargo Basket Fit for Nissan Xterra with Factory Crossbars
    In my research, I could not find standard specifications for crossbars when I looked in the Xterra's owner's manual. We have a Xterra in our shop today, and when I measured the crossbars, I agree with you that they seem to be approximately 3-1/2 by just over 1-3/16. The shape of the bars makes them a bit difficult to measure. With the crossbars on your 2010 Nissan Xterra at 3-1/2 inches wide, then the Curt Roof Cargo Carrier # C18115 will not be a fit for your crossbars. This cargo carrier...

If you find it too short for your crossbars, you do have different options: First, you can find a 4" wide U-bolt that is deeper than 2". RhinoRack Aero Crossbar Fit Kit # S280 is 4" wide and has 2-1/2-inches depth measured at the center indent.

  • Does Rhino-Rack Steel Mesh Roof Mounted Cargo Tray # RPBL-S280 Include Mounting Hardware
    The Rhino-Rack Steel Mesh Roof Mounted Cargo Tray # RPBL-S280 includes universal hardware to allow mounting on most all types of roof rack crossbars. The hardware will fit bars up to 3-7/8-inches in diameter as long as they are at least 50-inches long and spaced apart no more than 58-inches. The slight curve in your crossbars will not interfere with installation. You will want to take care to not over-tighten the hardware as this could cause distortion of the mesh carrier.
