The Hobie Compass/Compass Duo Cradle Set keeps your Hobie Compass or Compass Duo from getting damaged while its being transported on a trailer or a set of car racks. The cradles can be installed onto your trailer or the cross bars of your vehicle. The kit does not come with installation hardware but feature holes where bolts/washers can be used to attach the cradles. The foam pads on the cradles protect your kayak from scratches.
