Extension was perfect. Fit was great, I was a bit nervous as our Canyon basket is 7 years old and I was worried about everything lining up between new extension and old basket. Total time was about 20 or so minutes to assemble. Shipping was great, timed as expected, arrived in great condition boxed and wrapped. Shown on our 2024 VW Atlas Peak Edition.

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!

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

  • 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.

  • 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...

  • Best Roof Basket for Carrying Lumber
    I have a recommendation, but the Thule Canyon XT # TH859XT is not my first choice for carrying lumber mainly because of the wind fairing and the size. While the basket can be expanded to 70" long with the extension piece # TH8591XT, that is still not long enough for your lumber, and you'd have to load it at an angle, because of the lip where the wind fairing is at the front. To carry lumber I prefer the Yakima LoadWarrior Roof Rack Cargo Basket # Y07070-74. This rack has a center crossbar...

  • Fitting a Roof Cargo Basket to a Truck Bed Camper Shell With Thule Roof Tracks
    I have a solution for you, but its extremely unlikely that you'll be able to get the rack to line up properly with the tracks on your vehicle. Thule tracks have a matching fit kit for roof racks that includes the correct bolts to mount a roof rack as part # THKIT3101. These will fit the channel of the tracks properly and allow you to mount a roof kit. I reached out to Thule to help find the lowest-profile kit for you and we came up with the following kit: - Thule Rapid Podium Foot...

  • 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...

  • Will The TH8591XT Extension Fit An Older Thule Canyon 859 Roof Basket?
    The way your Thule Canyon 859 and the way the Canyon XT # TH859XT connect together will actually be different, so the extension will only fit the Canyon XT, unfortunately. I created a diagram showing what I mean. You may be able to find and extension for your Canyon somewhere out there, but your best option will most likely be to upgrade to the new Canyon XT # TH859XT and then get the # TH8591XT extension to go along with it.

  • 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.

  • How Tall is the Thule Canyon XT Roof Cargo Basket 859XT
    The 6" height that you referenced for the Thule Canyon XT # TH859XT is actually the overall height. This doesn't include the mounting hardware though. As long as you have more than 6" of clearance between your roof rack and garage opening the Canyon XT will fit! Whenever you do go to remove the basket it is actually quite easy. If you check out the attached photo you can see how the mounting hardware installs with just a U-Bolt and the hand-tightening knobs. I have also attached a review...

  • How Many # TH8591XT Extensions Can Be Used w/ Thule Canyon Roof Mounted Cargo Basket
    According to my Thule representative, they do NOT recommend using more than one # TH8591XT extensions. Once additional extensions are added, the basket will lose its structural rigidity and can sag.

  • Recommended Roof Basket for 1-1/2 Inch Tall Crossbars on GMC Savana Van
    The Thule Roof Mounted Cargo Basket # TH859XT referenced in your question is compatible with a wide array of crossbar sizes. This roof rack will work for you as long as your crossbars are spread apart between 20 inches and 37 inches. This roof basket has an optional extension in part # TH8591XT and optional lock in the part # TH450400. You could also take a look at a similarly priced basket like the Curt Roof Mounted Cargo Basket # C18115-117. This basket is 64-1/2 inches, and it is...

  • 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 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.

  • Recommended Roof Rack And Cargo Carrier For 1999 Chevrolet Express Van Hightop Conversion
    For your 1999 Chevrolet Express Van 1500 that is a Hightop Conversion I recommend the Inno Roof Rack System that uses 65" Inno Square Crossbars # INB165 and 9 7/8" Tall Inno Feet for Square Crossbars # INMDK that will offer a 132lb weight capacity. These feet will attach to the rain gutters on your roof, and give you enough additional height to clear the conversion roof. It may be possible to use the shorter 7 1/2" Tall Feet # INSD but you will need to measure from the rain gutter of your...

  • Recommended Cargo Basket for a 2022 Toyota Highlander LE
    The Thule Canyon XT Roof Cargo Basket item # TH859XT-8591XT you were looking at includes the 20" extension piece item # TH8591XT. This makes the basket 69" long x 40" wide x 6" tall instead of only 49" long. This roof basket will attach to your 2022 Toyota Highlander LE's factory crossbars.

  • Will the Thule Canyon XT TH859XT Fit a 2013 Subaru WRX Hatchback
    Yes, I checked with Thule and the Thule Canyon XT Roof Cargo Basket part # TH859XT is a confirmed fit for your 2013 Subaru WRX Hatchback. If you like, you can also add the Thule One-Key System Lock Cylinders part # TH450400 which will allow you to lock the basket to your vehicle or the Extension Piece part # TH8591XT to provide you with an additional 20" of space.

  • Will the Thule XT Roof Basket Extension Work for a Honda Roof Basket?
    I confirmed with my contact with Thule that the Extension Piece for Thule Canyon XT Roof Cargo Basket # TH8591XT will fit your Honda roof basket if it is the identical model to the Thule Canyon XT Roof Cargo Basket # TH859XT. My contact confirmed that Thule has made baskets for Honda in the past. If you can provide me with the model number of your Honda Roof Rack, I would be happy to provide you with a more confident answer.

  • Bolt On Roof Rack/Basket For 2018 Polaris RZR XP4 Turbo
    Having had a Side by Side, I know some of the trails can get pretty hairy and rough. Those rough rides are what really take a toll on your equipment, so I would recommend keeping it as simple as you can. We do not carry parts for your specific situation, but I can lead you to the system that I would use to get the best result. Since you are customizing your rig, drilling will be required. If you are okay with that, then the Rhino-Rack Roof Rack Legs - Fixed Mount - Item # RFMPC you suggested...

  • Will a Roof Mount Cargo Basket Fit a 2006 Jeep Commander with a Large Sport Roof Rack
    You will need to measure the width of the crossbars on your 2006 Jeep Commander. If they are less than 4 inches wide, you can use the Thule M.O.A.B., # TH690, that you have referenced. I have included a link to a video showing the basket on a different vehicle. Rhino Rack offers several baskets that will fit on crossbar widths up to 3-7/8 inches wide. Another option is the SportRack Cargo Basket, # A21030. If the crossbars are less than 3-1/2 inches wide, you can use this basket. If...

  • Best Placement for Rooftop Cargo Basket on Truck Topper
    There isn't a specific formula for where to place your Thule Canyon XT # TH859XT cargo basket on your truck topper, but generally having your cargo centered on your roof provides you with the most stability so I would be inclined to move it as close to the middle of those tracks on your topper as you can. It does look like you have quite a bit of room still so you may consider using the Extension Piece # TH8591XT which will add 20" of length to the Canyon XT so you can get as much cargo...

  • Roof Basket Recommendation for a 2013 Subaru Outback with Factory Crossbars
    The Rhino Rack Roof Mounted Steel Cargo Basket # TH859XT is an excellent choice for you. It is very versatile and fits most crossbar spreads and configurations. I agree, the size is great at 49" long x 40"wide x 6" tall. But did you know that you can get more length with the optional extension part # TH8591XT? You can also add locks to secure the basket to your roof racks in the part # TH450400. This carrier also comes with a limited lifetime warranty.

  • Recommended Rooftop Cargo Basket for 2005 Ford Escape with Factory Roof Rack
    The Surco Safari Rack 5.0 Rooftop Cargo Basket # SPS4550-Y400 is designed specifically for installation on Yakima brand roof racks but we do offer cargo baskets that will work on the factory-installed roof rack on your 2005 Ford Escape XLT. All you need to do is measure your cross bars. You'll want to measure their center-to-center spread and also the bars' own width and height as these factors determine which rooftop basket will fit on your rack. Some baskets require your bar spread...

    If your 2012 Jeep Patriot has crossbars are spread apart between 20 inches and 37 inches, the Thule Roof Cargo Carrier # TH859XT is a good fit. This cargo carrier is 49 inches long and the Thule Cargo Basket Extension # TH8591XT will add an additional 20 inches to that. You could always purchase the basket first to ensure a proper fit, then purchase the extension later if needed. The basket has a weight capacity of 150 lbs, but check your vehicle owners guide to ensure your roof can handle...

  • Roof Cargo Basket Recommendation for a 2016 Subaru Forester with Subaru Crossbars
    The Thule Canyon XT roof basket part # TH859XT that you referenced is a confirmed fit for your 2016 Subaru. It will fit crossbar spreads that are between 20 inches and 37 inches apart. Some carriers do not have an open range of spread for crossbars. Some have a few set positions that are only conducive to adjustable bars. The Thule extended carrier can be purchased two ways. You can order the main rack # TH859XT and the extension #TH8591XT, or you can order them together as one...
