Thule 710501 Evo Clamp Foot Pack is designed with unique, patented clamping technology to simplify securing the Foot Pack to the Load Bars and Fit Kit. Once the bar system is assembled, attaching to your vehicle is quick and easy. Thule's Evo Clamp feet have unique styling and a solid fit on vehicles with smooth, gutterless, naked rooftops. The Evo Fit Kit brackets use a simple click-in attachment point on the Evo Clamp Foot. The Evo Clamp Feet use a front facing adjustment mechanism which makes firmly attaching and positioning the bars easy and secure. The Evo Clamp Feet are safely secured to the vehicle using an ergonomic torque limiter key tool which clicks once the correct assembly tension is applied. Thule's Evo Clamp Foot Pack design is one of the easiest to install and safest roof racks on the market. The Evo Clamp Feet, combined with a Thule Evo Fit Kit and a pair of Thule WingBar Evo Crossbars, Square Crossbars or ProBars, offers a sleek, dependable roof rack that rests directly on the roof of your vehicle and fastens to your door jambs. Rubber base pads and coated door jamb clips assure a firm attachment that is gentle on your vehicle.
