3M™ DBI-SALA® Permanent Detachable D-ring Roof Anchor Base Assembly For Wood 2104534, with Flashing, Fits 2 x 4

3M's anchorage connectors are built from quality materials providing high strength and durability to stand up to tough environments. Anchorage connectors are the foundation of most fall protection systems, often overlooked but critical components because they securely attach your system to the anchorage. Your choice of anchor depends on the type of work being done. Anchorages are sold 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 and must be capable of supporting a load of 5,000 lbs. (22kN) or of meeting OSHA’s criteria of a 2-to-1 safety factor.
