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

If it's like a champ. It's OEM quality tool. I recommend it and would buy it again

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!

  • 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...

  • Fit & Compatibility of Rooftop Cargo Carrier for Factory Installed Roof Rack on a 2015 Honda Odyssey
    The maximum load for your vehicle is 1,340 lbs this includes passengers and cargo. To determine the cargo weight load limit you will want to take this number and subtract it from any weight and passengers weight in the vehicle. I was unable to determine the capacity of your factory roof rack but generally speaking roof rack systems aren't rated for over 165lbs. To find a rooftop cargo carrier that is compatible with your factory roof rack system you will want to determine the center...

  • 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...

  • 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.

  • Which Cargo Bag Would Be Best For My Roof?
    If you're looking for just the bag, this is the one you need. etrailer Cargo Bag w/ Mounting Straps - Water Resistant - 20 cu ft - 59" x 24" x 24" Item # 988501. I've put our bag to the test! Don't worry about water getting inside the bag, after the test all the contents of the bag were bone dry. If you don't have a roof rack you will want one because you will have a hard time strapping any bag you choose on your roof. Getting a roof rack system will help tremendously with strapping down...

  • 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...

  • 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.

  • Will the Thule Roof Cargo Basket, # TH859XT Fit a 2003 Honda CR-V
    Since the crossbars on your 2003 Honda CR-V are 3 inches wide, the Thule Canyon Roof Cargo Basket, # TH859XT, will fit. This basket fits crossbar spreads of 20" to 37". You will need to measure the center to center distance between the crossbars and compare it to this range, however, it sounds like you are in that range from your question. So this basket is a fit for your CR-V. Adding the extension, # 59505, fits in the center of the basket extending your rack 20 inches. I have included...

  • 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.

  • Will Thule Cargo Basket and Rhino-Rack Cargo Basket Fit 2015 Toyota 4Runner With Factory Crossbars
    Yes, both of the roof baskets you asked about, the Rhino-Rack Roof Mounted Steel Cargo Basket # RMCB and Thule Canyon XT Roof Cargo Basket # TH859XT will fit the factory crossbars on your 2015 Toyota 4Runner. Between these two options I strongly recommend the Thule Canyon basket because it has a larger space to carry your cargo than the Rhino-Rack, can be locked with Thule One-Key System Lock Cylinders # TH450400 while the Rhino-Rack does not have that option, and comes with a lifetime...

  • Roof Basket Recommendation for Rhino Rack Roof Rack on 2015 Toyota Tundra With CrewMax Cab

The weight capacity on the Thule Roof Basket # TH859XT is 150 pounds. You can add the 20 inch extension part # TH8591XT the the Thule Canyon and still use the same spread and maintain the 150 lb weight capacity....

  • Will Curt Extension Work On the Thule TH859XT Roof Cargo Basket
    I do have a solution for you, however the Curt Extension # C18117 referenced in your question is not compatible with the Thule Roof Cargo Baskets.

  • 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.

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.

  • 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.

  • 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...
