The Thule 687B Atlantis 1800 Rooftop Cargo Box updates a classic design that has been proven to work by the test of time. The Thule Atlantis 1800 provides giant storage capacity and great looks for large wagons and SUVs. The Atlantis comes pre-installed with a new QuickGrip mounting system so you'll be on the road in seconds, and mounts directly to most after-market and factory-installed roof racks. This cargo box not only lets you access your gear from either side of the car using Thule's patented Dual-Side opening feature, but is easy to open and close with an improved locking system that features a user-friendly, padded key and readable decal. And as always, Thule's built-in safety feature means that the key can only be removed when the box is fully closed, so you don't accidentally lock yourself out. The Atlantis have an eye-catching design, sleek black finish that compliments the aerodynamic lines of today's new car designs, measures 34.4 x 84 x 16.9 inches (W x D x H), and has a load capacity of 18 cubic feet.
