The Swivel-D anchor is a fully articulating anchor that rotates 360-degrees and swivels 180-degrees. It can attach to virtually any structure including steel, wood and concrete. It is manufactured with a heavy-duty stainless-steel shackle and a zinc plated 2 in inside diameter forged steel D-ring. It is a highly durable anchor that can be used for either temporary or permanent installation on the interior or exterior of your building or structure. This anchor is very universal in it's application as it can be bolted directly to numerous anchors already manufactured by SAS including our CRA Threaded Top Anchors/Risers, D-Plate Anchor, 2x-Member Wood Purlin Anchor, Corrugated Metal Roof Block, Standing Seam Anchor and more.
