DBI/Sala Sayfline Synthetic Horizontal Lifeline Systems for Mobi-Lok Vacuum Anchors are easy to install and extremely lightweight with a 11/16" (17.5mm) static kernmantle rope lifeline. These systems are used to protect workers operating in the horizontal plane who may not have continuous access to suitable anchorage points. Engineered with DBI-SALA attention to quality and detail, the Sayfline system will work alongside you during maintenance, bridgework, construction and general industry applications with absolute safety and reliability. A horizontal lifeline may appear to be a basic line strung between two anchors, but it is not. It is critical to choose a system that has been precision engineered and rigorously tested to meet regulations. DBI/Sala Sayfline Synthetic Horizontal Lifeline Systems for Mobi-Lok Vacuum Anchors include integral tensioners for easy set-up, dual energy absorbers designed to limit fall arrest forces, and a carrying bag. These 2-worker capacity systems are available in various lengths to suit jobsite needs, and are equipped with i-Safe.
