Great fit this etrailer is one stop shopping for all your travel needs!!!!!

Extension worked great. Just wish they sold them in one foot lengths . The two extra feet was a little too much for my Cherokee



by:

Great service and fast shipping by etrailer! Strongly recommend this company.

UPS didn’t deliver to my door which was concerning as any passerby on the road could have stolen my delivery but not your company’s fault. Other than that perfect!

  • Will Thule Roof Cargo Basket with Extension Fit a 2014 Jeep Cherokee
    The Thule Cargo Basket part # TH859XT with the extension part # TH8591XT will fit your 2014 Jeep Cherokee with factory crossbars. I attached a review video that shows the basket being used on a 2014 Cherokee just like yours. The extension section would work just fine and realistically would just make the basket 20 inches longer. The total length would be 69 inches so you can measure that length on your roof. You can also buy these two together as part # TH859XT-8591XT.

  • Will Thule Roof Cargo Basket and Extension Fit a 2006 Lexus LX 470 with Factory Roof Rack
    The Thule Canyon cargo basket # TH859XT and extension # TH8591XT fit on crossbars that are spaced apart between 20" and 37". This crossbar spread is measured from center to center. The Thule Canyon with extension # TH8591XT is a confirmed fit for your vehicle and can be bought separately or together in part # TH859XT-8591XT.

  • Would the Thule Roof Cargo Basket Extender make the Basket too Long for a Ford Explorer
    The overall length of the Thule Roof Mounted Cargo Basket, part # TH859XT, is 49 inches long. The extender, part # TH8591XT, adds 20 inches. This would bring the overall length of the rack to just 69 inches. I would take a tape measure length of the roof on your Explorer. You would then be able to see how the rack would fit on your roof. The rack attaches to the bars and the crossbars must be between 20 inches and 37 inches so the crossbars must be in that range of distance apart.

  • Net for Thule TH859XT-8591XT Canyon XT with the Extension
    The Curt Stretchable Cargo Net, part # C18201 with an unstretched dimension of 38 x 65 would fit the 69 x 40 Thule # TH859XT-8591XT Canyon Cargo Basket with Extension absolutely perfectly. I've linked to a product video featuring the Thule Canyon XT cargo basket.

  • Recommended Low Profile Roof Basket for Yakima JetStream Crossbars
    I do have a solution for you, however the Inno Shaper 100 Roof Cargo Basket # INXA569 referenced in your question will not work with the T-channel on your Yakima JetStream Crossbars. The channel dimensions on the JetStream bars do not match up with the mounting hardware for the Inno Basket. For your Yakima roof rack, I instead recommend the Thule Canyon roof cargo rack, # TH859XT. This is another low-profile basket that will actually clamp around the aero-style bars on your vehicle instead...

  • Roof-Mounted Cargo Carrier Recommendations for 2006 Toyota Tundra
    If you have an existing roof rack system, the Thule MOAB Roof Top Cargo Carrier # TH690 is a compatible fit for your 2006 Toyota Tundra Double Cab. The size is custom-made for your vehicle, provides a quick, hassle-free assembly, and includes two adjustable Thule load bars that can be used for bike, ski, and water sport carriers. I have provided a link to a video showing the installation of this product on a 2013 Honda Ridgeline. While this isn't the same vehicle as yours, it is a similar...

  • Comparing Thule Canyon XT vs Yakima OffGrid Roof Basket for 2020 Tesla Model 3
    As a petite 5'2" Ecuadorian girl, I can totally relate, so I'm happy to make a recommendation! Based on my research, your 2020 Tesla Model 3 factory roof rack system has a crossbar spread of 28 inches. This means that both the Thule Canyon XT # TH859XT and the Yakima OffGrid # Y07138 are compatible with the factory rack on your Model 3. Both roof baskets have the capability to accept a variety of roof mounted accessories. The Yakima OffGrid actually has two adjustable accessory bars, which...

  • Recommended Roof Basket for 2018 Subaru Crosstrek with OEM Crossbars
    The Curt Roof Mounted Cargo Basket # C18115-117 is not test fit to any vehicle according to my contact at Curt. We haven't tested on Subaru OEM crossbars but we do know that it fits crossbars up to 3" wide x 1-5/8" tall. For a fit on your bars, I can recommend the Thule Canyon Cargo Basket - 49" Long x 40" Wide x 6" Deep # TH859XT which is versatile enough to fit most crossbar spreads and configurations. This rack also has an optional extension # TH8591XT and optional locks # TH450400.

  • Rooftop Cargo Basket for Use on 2014 Nissan Murano with Factory Roof Crossbars
    You're correct that the Curt rooftop cargo basket # C18115 requires specific crossbar spacing for installation. This basket will not be an ideal fit on your Murano but we can definitely find one for you! We offer the Thule # TH859XT that will work with a 20-inch - 37-inch crossbar spread and we also have baskets like the Rhino-Rack # RMCB that work within a wide range of bar spreads, from 21- to 30-inches. This makes this basket a great choice if you need the flexibility to use it on another...

  • Roof Cargo Basket for 2015 Jeep Grand Cherokee with Rhino Rack Crossbars 29 inches Apart
    The Thule Canyon XT part # TH859XT will fit your crossbar spread easily and would work well for you. It has an optional 20" extension, part # TH8591XT and optional locks to lock the rack to the crossbars to prevent theft in part # TH450400. Your 44 X 35 cargo bag will fit perfectly in this rack.

  • Best Inexpensive Roof Cargo Basket with Extension for a 2010 Subaru Outback
    Too long or not is a matter of opinion! Provided the Thule basket, # TH859XT, fits now, it will still mount to your 2010 Subaru Outback using extension # TH8591XT. The extension adds 20 inches total to the length of the basket making it 69 inches long but it does not change the installation process at all. You could change the arrangement of the feet to make the basket more forward or rearward on the crossbars if needed. Compare the overall length to the roof length to determine if the...

  • Options to Carry a Roof Basket on a 2018 BMW X3
    I do have an option for you but as of (April 2018) we do not have any custom fit roof racks confirmed to fit your 2018 BMW X3. Therefore, in order to use a roof basket you will want to use a universal roof rack like the SeaSucker Monkey Bars Roof Rack part # 298-SX6000B which mounts to the roof via vacuum cups and will not require any modifications to the vehicle. Then for a roof basket I recommend the Thule Canyon XT Roof Cargo Basket part # TH859XT. The Thule Canyon has a built-in fairing...

  • Would the Thule Roof Mounted Cargo Basket # TH859XT fit Factory Crossbars of a 2014 Subaru Forester
    The Thule Roof Mounted Cargo Basket # TH859XT is designed to fit crossbars that are spread apart a distance between 20 inches and 37 inches. If you measure yours and it is in this range, then this rack will work for you. If you were to use the extension piece part # TH8591XT, crossbar spread would not change.

  • Is a Third Crossbar Required when Adding an Extension to Thule Roof Basket TH859XT
    Having a third roof rack crossbar is not a requirement for adding extension # TH8591XT to the Thule Canyon XT cargo basket # TH859XT. The carrier will be mounted to the roof racks in the same manner, with or without the extension.

  • Largest Cargo Basket Recommendation for a 2008 Ford Expedition EL
    Sounds like you are looking for the largest cargo basket available that is confirmed to fit your 2008 Ford Expedition. I checked with Thule and the Canyon XT part # TH859XT has been confirmed to fit your vehicle. When you combine it with it's extension piece # TH8591XT you would have a cargo basket that is 64 inches long by 40-3/4 inches wide by 7-1/4 inches tall.

  • Does Thule Roof Mounted Cargo Basket Need Added Stability?
    It won't be necessary to add a third roof rail for added stability to use the Thule Roof Mounted Cargo Basket # TH859XT along with Cargo Basket Extension #TH8591XT on your 2004 Jeep Grand Cherokee. You might also consider locks for this basket, # TH450400 to deter theft of your basket. I've added a link to a video review of this basket for you to take a look at.

  • Will Thule Roof Mounted Cargo Basket TH859XT Fit a 2007 Toyota 4Runner
    The # TH859XT Thule roof mounted cargo basket is designed to fit most OEM roof rack bars of all sizes. This rack requires that the crossbars be situated between 20 inches and 37 inches apart. If you are in this range then this will be a great basket for you. An extension, part # TH8591XT is available for the # TH859XT basket, if needed. We also offer a large selection of cargo bags designed for use on roof top baskets. The Rightline Ace 2 Rooftop Cargo Bag, part # RL100A20 offers 15...

  • Will Thule Roof Cargo Basket and Extension Fit a 2010 Jeep Grand Cherokee Laredo
    Thule roof cargo basket # TH859XT is designed to fit a wide variety of crossbars. The crossbars must have a center to center distance from one crossbar to the other anywhere between 20" and 37". If the crossbars on your 2010 Jeep Grand Cherokee Laredo fit the above description then the basket plus extension #TH8591XT will fit. There is also an optional lock available in part # TH450400.

  • Will the Thule Cargo Basket Fit a 2009 Toyota Tacoma Double Cab with Factory Roof Rack
    To determine the fit of the Thule cargo basket # TH859XT you will need to measure the crossbars on your 2009 Toyota Tacoma double cab. This basket fits bar spreads of 20" - 37 inches. Adding the extension # TH8591XT would not change this required crossbar spread range.

    Yes, the Rhino-Rack Aero Bar Roof Rack for Camper Shells - Track Mount - Black - Standard - 59" Long, Item # Y02-490B is a confirmed fit for your 2003 Ford F-150 Supercrew with a naked roof. For a cargo basket then the Thule Canyon part # TH859XT would fit as long as the spread of your crossbars are between 20" - 37". This rack fits most situations so measure it up, I think it will work for you! This rack also has an extension available in part # TH8591XT which gives you an additional...

  • Can I Use the SUP Taxi Paddleboard Tie Down with a Thule Canyon Cargo Basket
    I have a solution for you, but even with the 20" Extension # TH8591XT added to the Thule Canyon # TH859XT, the Canyon is only going to be 69" long and I can't imagine that you'd be able to fit a full sized paddleboard inside it. Additionally, the Thule SUP Taxi # TH810001 is not designed to fit on the bars of the Thule Canyon securely so that's not really an option. With that said, both the Canyon and SUP Taxi can be easily installed and removed as needed, so you can just remove the Canyon...
