Ask the Experts about this Thule Roof Box

  • Adding Kayak Carrier and Roof Box to Rhino-Rack Pioneer Platform
    The Thule Force XT Sport Cargo Box # TH6356B measures 24-3/4 inches wide and the Rhino-Rack J-Style Kayak Carrier # S512 will take up about 24 inches of crossbar space when it's in its upright position for a single kayak. This width might increase if you have a larger kayak that requires you to adjust the J-cradle down a bit. Both of these mounted side by side will get you extremely close to if not over the 49 inch overall width on your Rhino-Rack Pioneer Platform Rack like # JA9133....

  • Do the PowerClick Clamps on the Thule Force XT Roof Boxes Ever Stop Clicking
    The PowerClick Clamps on the Thule Roof Boxes such as the Thule Force XT part # TH6356B will produce an audible click once tightened properly. The audible click will be heard each time the knob is turned while tight. It sounds like this one may be damaged so replacement, part # 1401467300, is what I recommend. If the clamp is not working like the others then that's a good sign it is defective.

  • Will Thule Force XT Sport Allow Hatch on 2016 Honda CR-V to Open
    For the Thule Force XT Sport Rooftop Cargo Box # TH6356B to allow the hatch on your 2016 Honda CR-V to fully open without interference you need to have at least 48-1/4" from the middle of your forward most crossbar to the line where your roof and your hatch meet up. From what I could find it looks like this shouldn't be an issue for you. I'm not really sure where your antenna sits in relation to your crossbars so it is a little hard to determine if the Force XT Sport will clear it but...

  • Cargo Box for 3 Snowboards for a 2016 Subaru Impreza Hatchback
    If your 2016 Subaru Impreza hatchback came with the factory roof rack including the crossbars that run side to side then I recommend the Thule Force XT Sport # TH6356B. This box will hold up to 3 to 4 snowboards up to 175cm long. If your Impreza does not have the factory crossbars or the factory side rails then you would need to add a roof rack. For a model without any sort of rail or bar on the roof you would use the 47 inch SquareBars, part # TH712200, along with the Evo clamp feet,...

  • Will Thule Force Alpine # TH623 Clear Rear Antenna Fit of 2014 Toyota 4Runner
    I looked up pictures of the antenna/fin you have on the rear of your 2014 Toyota 4Runner and it only appears to be slightly taller than the top of the roof rack crossbars, so the tapered rear of the Thule Force XT part # TH6356B would pretty easily clear above it. If you check out the picture I attached you can see that the rear of the box angles up compared to where it mounts to the crossbars.

    For your 2016 Acura MDX with factory installed cross bars the Thule Force XT Rooftop Cargo Box # TH6356B is a confirmed fit and a great value. This fits as long as your two factory crossbars are spaced at least 23-5/8-inches apart from the center of one bar to the center of the other and no than 35-3/8-inches apart. You'll want to take a look at your MDX owner's manual for the car's roof weight capacity. Keep in mind that the weight of the box itself plus your loaded cargo needs to remain...

  • Use of Weather-Strip Material to Prevent Water Entering Thule Rooftop Cargo Box
    Virtually no manufacturer actually wants/encourages owners to modify their products; this is certainly true for Thule and their various cargo boxes. My contact there advised that Thule cannot recommend making such a change although I do understand your interest in making your rooftop cargo box as water-tight as possible. It is all but impossible to make a rooftop cargo box totally waterproof. My Thule contact did say that on older cargo boxes that have seen a lot of use sometimes the...

    I do have an option for you but I contacted Thule and the Thule Hullavator part # TH898 actually requires 38 inches of bar space to install so it would not fit on the 60" cross bar with the Thule Force XT Sport Rooftop Cargo Box part # TH6356B that is 25" wide.

  • How Much Weight Can I Carry in a Box on the Roof of a 2018 Toyota RAV4
    From my research your 2018 Toyota RAV4 can carry up to 101.9 pounds on the factory roof rack. That may be oddly specific but it's what Toyota states as the maximum. So you need to make sure the roof box you choose and everything in it doesn't exceed 101.9 pounds. A good roof box that you might like is the Thule Force XT Sport, part # TH6356B. It holds up to 11 cubic feet of gear and includes locks. It fits on your RAV4's crossbars with clamps that are super easy to tighten. You...

  • Rooftop Cargo Box Recommendations for 2017 Subaru Outback
    All rooftop cargo boxes will generate wind noise and to some degree all will negatively affect mileage but those with the more aerodynamic low-profile shape, such as Thule's Hyper XL # TH612, will tend to be quieter and will have slightly less effect on fuel economy. At 90-inches external length this is the longest box Thule recommends for your Outback. It can handle skis up to 201-cm in length so it may be more than you need. It also weighs 53-lbs empty so keep in mind that what you can...

    The roof box you have looks like it is a Thule box and we have the replacement lock core that should work for you. The problem you will have is that the box needs to be unlocked before you can swap out the core. You may need to get a locksmith to get the broken key out of the lock and then open it. You can then order the lock cylinder, part # THLOCKN022, the replacement key, part # THKEYN022, and you will need a universal change key, part # 853-1251. This allows you to remove the...

  • Thule Force XT Compatibility On Toyota 4Runner With Factory Roof Rack
    The Thule Force XT has one of my favorite mounting systems across all roof boxes. The clamps make it easily compatible with most roof racks. Your 2020 Toyota 4Runner factory rack is one of them.

  • Measuring to Determine Which Thule Cargo Boxes Fit a Lexus RX 350
    Front overhang for cargo boxes is not an issue of concern. Longer boxes will overhang the front some but most boxes have adjustable feet to allow you to have the box more forward or rearward on the vehicle roof. The area of concern is the back of the vehicle. Things like antennas and rear hatch doors can interfere with the cargo box. In order to determine which Thule boxes will fit without interference you will need to take one measurement. First, if the crossbars on your Lexus RX...

  • Roof Cargo Box and Kayak Carrier Recommendation to Fit 2019 Toyota Highlander with Factory Rack
    We have the Thule Force XT part # TH6356B which is 24-3/4 inches wide and has 11 cubic feet of cargo space. This would easily be narrow enough to also accommodate a kayak carrier. For that we have the Yakima JayLow part # Y04073 which is a J-style. This rack is padded, easy to load/unload, can fold down when not in use and could potentially carry a second kayak if needed. These both are a confirmed fit for the factory bars of your 2019 Toyota Highlander as well. The cargo box would...

  • Which Thule Cargo Boxes Will Fit Thule Square Crossbars on a 2007 Honda Fit Sport
    The choices of compatible Thule rooftop cargo boxes for the square load bars on your 2007 Honda Fit Sport will depend on several factors: the vehicle roof weight limit, the crossbar spacing and access to the rear hatch. A roof-mounted antenna may also interfere with some larger cargo boxes. The largest boxes from Thule will interfere with your rear hatch and/or your roof antenna. We offer several Thule cargo carriers that will definitely clear the rear hatch on your Fit. The 11 cubic-foot...

  • Kit Needed to Swap Lock Cores Out of Thule Force Cargo Box
    You can use a Thule Re-Keying kit part # TH450200 which comes with two new cores, two keys, and a change key. But to remove the old lock core will require you to unlock it first. Once unlocked you can insert the change key and the old core will slide right out. If you don't have a key to unlock what you have you'll need a key for it. To pick out the key you'd then want the part # THKEYNXXX where the X's equal your key number.

  • Can a Surfboard Be Carried on Top of Thule Force Large Rooftop Cargo Box # TH624
    Rooftop cargo boxes like the Thule Force L # TH6356B that you referenced are a great way to transport cargo items that need protection from the elements. However, these ABS plastic cargo carriers are not designed to bear any weight, only to carry the specified cargo weight of what is loaded inside them. I cannot recommend placing anything on top of this or any other plastic cargo box. Transporting any rooftop cargo on a vehicle requires that you observe the vehicle's maximum rated roof...
