Use the Thule XT Large Rooftop Box Cargo Carrier for hauling your precious cargo across town or country. Make road trips more comfortable, convenient and enjoyable when you free up the space in your car by moving your gear to the Thule Force XT L roof box. The Thule Force XT series of rooftop cargo boxes a stylish and aerodynamic cargo box which holds skis, small luggage or other gear. Thule packs in top-of-the-line features and advanced engineering to make the Force XT cargo boxes easy to use, durable and secure. The design improvements start with the unique angular, yet aerodynamic shape, it is constructed with durable, lightweight thermoformed ABS plastic. This is an automotive grade plastic, a material commonly used for the manufacture of automobile exterior components such as rearview mirrors, with a matte black finish. Care for the finish as you would the vehicle using soft sponges, microfibers, and sudsy water, but no automatic carwashes. The front of the box is smooth with no belt line found on other boxes, this reduces frontal area turbulence. The angular high and low areas of the lid are modern in design but also act to stiffen the lid with little to no added weight, this compared to other designs which use extra internal bracing for stiffness adding a material weight penalty. The Force XT series boxes are strong with a 165-pound carrying capacity, most other boxes are rated to 110 pounds. This is 55-pounds extra weight capacity, that's 33% greater than what most other boxes are rated to carry. The added strength can be attributed in large part to the steel reinforcements in the base which encompasses the mounting hardware, an area where high stresses occur. The lid to base overlap at the front of the box is greater than any other box, eliminating the possibility of "fish mouthing", this is an aerodynamic occurrence when air forces separation between the lid and base. No other manufacturer has engineered such a targeted solution to this phenomenon as effectively and elegantly. The LockKnob encompasses the lock cylinder housing, offering protection to the Thule Comfort Key and adding comfort when locking and unlocking your cargo box. The crossbar mounting hardware has extra wide crossbar attachments to accommodate a wide range of crossbar shapes and sizes. The smooth turning, rubberized knob tightens the hardware and clicks when fully tight. This click function ensures that the hardware is not over, or under tightened to the crossbar. The dual-sided opening lid allows for easy opening and closing from either the passenger or driver side of the vehicle. The Force XT boxes have been thoughtfully designed to provide the best possible clearance for the vehicle's rear hatch, spoiler, and antenna. The four primary sizes; Sport, L, XL, and XXL match up well to proportionate vehicle sizes.
