3M™ DBI SALA® anchorage connectors are built from top quality materials guaranteeing high strength and durability to stand up to tough environments. Anchorage connectors are a critical component in a fall protection system as they securely attach the users system to the anchorage. Your choice of anchor depends on the type of work being done. Anchorages are selected by what they connect to (general/all purpose, steel, concrete, roof or specialty), whether they are fixed or mobile, and whether they are permanent or portable. They all must provide a secure point of attachment for a complete personal fall arrest system.
