Get that roof rack setup you've always wanted. Start by installing the first step, the Thule Evo Clamp Foot Pack set. This set is perfect for vehicles that lack roof-rack attachment points. Patented clamping technology securely holds your rack to your vehicle. Easily install the feet with easy click-in mounting brackets. Ergonomic torque limiter keys indicate when the feet are properly secured to the vehicle. For additional protection, you can add theft-resistant lock cylinders (sold separately) to lock the feet to your vehicle.
