Thule SUP Taxi XT Crossbar Requirements

Thule Motion XT Alpine Alpine Cargo Box

Cargo boxes, bags, and baskets are great for transporting gear on your vehicle's roof. A cargo box has the added benefits of an aerodynamic shape that reduces drag and wind noise, a hard shell to protect your gear, and a higher degree of weather resistance. And you can latch and lock a cargo box for added protection against theft.

The Motion XT Alpine has 16 cu ft of storage space for golf bags, luggage, skis, snowboards, and other gear. The aerodynamic, low-profile design helps to reduce drag and wind noise, and the locking lid conveniently opens from either side of your vehicle. The box has internal tie-down points for securing cargo, and the PowerClick mounting system offers easy, tool-free installation.

Durable Construction

Thule Motion XT Alpine Alpine Construction

This cargo box is constructed of durable ABS plastic that is lightweight yet rigid and impact resistant. It has a glossy black, gel-coat finish that is stylish and less susceptible to chips, scratches, and harsh UV rays when compared with paint.

Dual-Side-Opening Lid

Thule Motion XT Alpine Alpine Cargo Box Dual Side Opening Lid

The Motion XT Alpine features a dual-side-opening lid so you can load and access your gear from either side of your vehicle. Integrated, grip-friendly handles help you easily open and close the lid even with one hand. The lid has lifters that ensure it opens and closes smoothly. There is also a convenient pull cord on the inside that helps you close the lid.

SlideLock System

Thule Motion XT Alpine Alpine Slide Lock System

The cargo box has SlideLock locks on each side of the lid. These locks have built-in indicators that let you know if the box is properly latched. The keys cannot be removed from the locks unless the lid is closed and locked. This prevents you from driving with an open or unlocked lid. The locks include Thule One-Key-System cores so you can swap them out to make all your Thule accessories keyed alike.

PowerClick Mounting System

Thule Motion XT Alpine Alpine Cargo Box PowerClick Mounting System

The box can be mounted on your vehicle in less than 5 minutes with the PowerClick mounting system. These clamps adjust along tracks in the floor of the box to accommodate different crossbar spreads.

Thule Motion XT XL Cargo Box Dials

To install the box, set it on your roof rack and center the clamps over your crossbars. Then simply turn the dials to tighten the clamps around the bars. The dials click when the clamps are secure.

Cargo Tie-Down Points

Thule Motion XT XL PowerClick Assembly

The PowerClick assemblies on the inside of the box have fixed anchor points for securing your cargo. Just loop the included cargo straps through the anchor points and pull the straps tight to secure your gear.

Review from a similar Motion XT Alpine in Roof Box

The ease of installing and removal of the unit is good. However it isn't a perfect fit. the roof box is a bit to long. With the box totally in the forward position the rear lift door against the box. This prevents the door lid from closing the door electrically. 600157

  • Recommended Thule Roof Box on a 2016 Toyota 4Runner with Thule AeroBlade Crossbars
    We have three recommended roof boxes confirmed to fit your 2016 Toyota 4Runner with AeroBlade Crossbars. The Thule Motion XT # TH629706, in black, or # TH629707, in titan glossy, is one of Thule's newest products. This box features a Slidelock system and locks automatically when the lid is closed. It installs easily using the turn dials to tighten the clamps. The Thule Motion XT Alpine # TH629506 also has the Slidelock system. It's over a foot longer than the Motion XT and several...

  • How Many Snowboards Can I Fit in the Thule Motion XT Alpine
    The Thule Motion XT Alpine # TH629506 is designed to carry between 3-5 snowboards, so the odds that you'll be able to fit 4 are pretty good; but this is obviously going to depend on the size of the boards and bindings. The internal dimensions on this box are 84-1/2" long x 33" wide x 11-1/4" tall, so as long as you don't have any extremely long boards this box should be able to handle 4 boards without issue. In the configuration you're mentioning you'll need to make sure that your bindings...

  • Low Profile Cargo Box and Crossbar Recommendation for 2013 Land Rover LR4
    Installing the Thule AeroBlade Edge Roof Rack, # TH7602-TH7603, and Thule Fit Kit for Podium Style Foot Pack, # THKIT3112, will increase the height of your 2013 Land Rover LR4 approximately 3 inches. As you stated, the Thule Motion XT Alpine Rooftop Cargo Box, # TH629506, measures 12-1/4 inches at it's tallest point from the top of the crossbars. This cargo box combined with the roof rack system will add approximately 15-1/4 inches to the height of your LR4.

  • Will the Thule Motion XT Alpine Rooftop Cargo Box Fit a 2018 Honda Odyssey
    In order to install the Thule Motion XT Alpine Rooftop Cargo Box part # TH629506 on the roof of your 2018 Honda Odyssey you will need crossbars spaced between 23-5/8" - 36-7/8" apart on center. If you do not already have crossbars on your vehicle or the ones you have cannot be moved to fit the above criteria then I recommend the Rola Rail Extreme RBU Series Roof Rack part # RBU60. This system has aero shaped crossbars for wind resistance and integrated channels for use with channel mounted...

  • Low Profile Roof Cargo Box and Roof Rack Recommendation for 2019 Jeep Grand Cherokee Limited
    The lowest profile roof rack that fits your 2019 Jeep Grand Cherokee Limited that has the black and chrome roof rails is the Thule Aeroblade Edge rack part numbers # TH7602B-TH7602B and # THKIT3142. Since this has a flush bar setup where the crossbars do not stick through the feet of the rack it's able to be a bit shorter. The lowest profile box then that fits this rack is the Thule Motion XT Alpine part # TH6295B which only measures 13-1/4 inches tall. Most are at least 4 inches taller...

  • Thule Roof Box Compatible with Factory Roof Rack on 2018 Honda CR-V with Sirius Antenna
    The Thule Force XT Rooftop Cargo Box - 18 cu ft - AeroSkin Black # TH6358B fits maximum crossbar dimensions of 3-1/2" wide x 1-11/16" tall and requires a crossbar spread between 23-5/8" and 35-1/2" on center. It also requires 51-1/8 inches between the front crossbar and the line where the roof and hatch meet to confirm there won't be contact with the hatch and you will have full access to your rear cargo. Thule does not confirm the fit, so I recommend taking the measurements to see if...

  • 2018 Volvo V90 CC Ocean Race Roof Cargo Box Recommendation
    Probably the closest Thule Cargo Box to the one Volvo sells is the Thule Motion XT Rooftop Cargo Box # TH629506 which is black or the Silver # TH629707. It has similar cut outs where the mounting hardware is. It's not a total match though as the rear is shaped differently. This will fit the factory bars of your 2018 Volvo V90 though which are Thule bars. To determine if this will allow your rear hatch to open will require you to measure from the center of your front crossbar back to...

  • Lo Profile Cargo Box Options for a 2006 Toyota Highlander with Factory Roof Rack
    So basically you want to keep the overall height of the 2006 Highlander including the cargo box under 7 feet tall. If the height of the vehicle itself is 5 feet 9 inches tall then that leaves 15 inches to work with. Like you said you could use the SkyBox Lo, # Y07338, since it is 11-1/2 inches tall. You could also use: Thule Pulse Alpine, # TH613, at 12-1/2 inches tall Inno Wedge, # INBRM660BK or # INBRM660WH, at 11 inches tall Inno Shadow, # INBRA1150BK, at 11-3/4 inches tall Inno...
