The Thule 480r Complete Rapid Traverse WingBar Evo Car Roof Racks for Naked Roof-tops incorporate Thule's latest foot design, providing a superior, dependable fit. The Thule Traverse roof rack fits vehicles with smooth, gutterless, naked rooftops (without attachments or railings). The Rapid Traverse Foot Pack incorporates three, unique, integrated components: EasyClick Bracket Attachments, OneTouch Bar Locks, and the AcuTight Tension Tool. The Easy Click Bracket Attachments allow you to insert and snap the fit kit clips into place in seconds. The One Touch Bar Locks snap down and hold your crossbars in place (once they are set to the correct position). The AcuTight Tension Tool has a built-in torque meter that tells you when your rack is tightened properly to your roof. The rubber padded Rapid Traverse 480r Foot rests on the roof of your vehicle and is designed exclusively for use with Thule WingBar Evo Load Bars. Thule's Traverse Fit Kit securely attaches the Rapid Traverse Foot Pack to the rooftop. The 480r Complete Rapid Traverse Rack includes a set of four 480r Rapid Traverse Feet, two Aluminum WingBar Evo Load Bars, four End Caps, and one Traverse Fit Kit (specific to your vehicle). Thule's recommended load bar length will be provided. Thule lock cores are recommended (sold separately - see below).
