This listing is for TWENTY (20) tie down attachments.
The strong surface mount d-ring has a 4,000 lb. vertical pull weight rating*. The ring is welded together, not pressed. It's gradual taper creates a low profile tiedown attachment rising only 3/8" off the floor.
This steel attachment is zinc coated to inhibit corrosion. To obtain maximum strength it is recommended to install these d-rings with bolts, lock nuts, and fender washers (wide diameter).

*RATED CAPACITY: Also known as "assembly capacity" or "break strength" is the minimum load a complete assembly can withstand before failure in a laboratory pull test when the product is NEW.
WORKING LOAD LIMIT: The maximum load weight a tie-down should be subjected to during normal use. To assist in making the proper tie-down choice the Federal D.O.T. requires the W.L.L. to be 1/3 of the Rated Capacity.
