The Thule Top Mounting Rail is an upper reinforcement profile designed specifically for rear-mounted Thule motorhome bike racks.

Installed through the vehicle wall, it helps spread the load evenly across the panel, improving stability and reducing stress on the mounting surface.

Its extended profile allows greater flexibility when positioning fixing points, making it easier to align with existing structures inside the rear wall. Ideal for secure, long-term installation of all Thule rear mounted motorhome bike racks, including the Sport G2 and Elite G2 range.
