DBI-SALA® Concrete D-Ring Anchors have a rugged design for harsh environments and provide a simple, versatile and safe concrete anchor solution for use in temporary or even permanent applications. A safe “hook-up” indicator notifies the user the anchor has been installed properly and the reusable D-ring assembly is ready to use again by just installing a new bolt. For flexibility, install into 11/16” or 3/4” holes so only standard drill bits are needed. Model #2104560 has 1 anchor bolt; Model #2104561 has 5 anchors bolts, Model #2104562 has 11 anchor bolts and Model #2104564 has no anchor bolts. All models are 5,000 lb rated and the OSHA compatible connection point swivels 360 degrees for safety and usability. Meets or exceeds all applicable industry standards including OSHA, ANSI and ASTM E488 Standard Test Methods for Strength of Anchors.
