This kit allows you to extend the lifelines to attach to your stern railing. The Vinyl coated stainless steel lifelines have solid stainless gate hooks for easy boarding from docks. Stern Rails and cabin top rails were not standard as new from the factory, but in order to have lifelines you would need both. Unfortunately, both the M19 stern rail and cabin top rails are no longer available.
This package does require a "Nicopress" swaging tool and a cable cutter for installation. Most marine supply stores loan or rent professional tools.
