Mounting screws are NOT included in package;different screws are needed for fiberglass and wood applications. Therefore you can purchase your mounting hardware at your local hardware store. If you are looking to use this track with any of our rod holders, please look at product #5920 adaptoer plate. This will convert any of our rod holders to slide within the track system.
