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.

  • 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.

  • Will the Thule Canyon XT TH859XT with Extension Piece 8591XT Fit a 2018 Subaru Forester
    Yes, you can use the Extension Piece for Thule Canyon XT Roof Cargo Basket part # TH8591XT with the Thule Canyon XT Roof Cargo Basket part # TH859XT on your 2018 Subaru Forester. The overhang of the basket will just be more but you can choose to have this in the front, the rear, or split for the front and rear. I recommend you pick the position that allows you to still open your hatch fully.

  • 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.

  • 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.

  • 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...

  • 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.

  • 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.

  • 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.
