The Rhino-Rack RL Legs are specially developed foot kits for attachment to standard rain gutters on a vehicle. These are mostly found on older or commercial vehicles. This is a very stable attachment, and the number of feet is also flexible in most cases.
They are compatible with HD crossbars. A combination with a PioneerNG platform or Vortex crossbars requires the installation of the adapter kit GPC29-50-16VA-FK1
