"Add a convenient hard point between the ribs of your truck bed, or any location with limited space. The VersaTie Slimline Anchor Plate Assembly is similar to our standard Anchor Plate Assembly, but with two sides of the anchor plate machined, making it narrow enough to accommodate installation in the valleys of your corrugated truck bed. Like our standard anchor, the Slimline model requires only two small holes be drilled in the main structure for easy installation. Each anchor plate assembly is designed to a 3,000 lb. Minimum Breaking Strength (MBS) in vertical pull and a 2,000 lb. MBS at 45°, with a recommended working load of one-third MBS. The tie-down ring swivels freely to prevent binding and ensure good load alignment. Sold as a pack of four, the tie-down ring swivels freely to prevent binding and ensure good load alignment. Because they're removable, they're a great option when a tie-down point is only occasionally needed, leaving only the smooth, contoured black anodized anchor plate visible. This anchor plate assembly includes one single-stud tie-down ring, one anodized Slimline aluminum anchor plate, one stainless steel backing plate, two whiz nuts and two ¼"" stainless steel machine screws."
