Utility D-ring Tiedowns - 3,500 lb. Capacity Steel Tie Down Anchors - 20 Pack This listing is for TWENTY (20) steel tie down attachments. D-rings are a simple and versatile way to secure cargo loads. Simple bolt on mounting is all that is required, or you have the option of welding these directly to a steel platform. They can be used for securing cargo in a trailer, van, camper, pickups etc., or for hanging tools in a shed or garage. A strong 3,500 lb. breaking load capacity (straight pull). W.L.L. is 1,167 lb. capacity - 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 WLL to be 1/3 of the Rated Capacity. Both pieces are made from steel and plated with a zinc coating to inhibit rust and corrosion. The ring is fused together, not compressed, therefore preventing the ring from pulling apart. We recommended installing these d-rings with 1/4 bolts, nylon lock nuts, and fender washers (wide diameter). SPECIFICATIONS: Please see secondary image in the gallery. Here are the written specs: The 3/16 diameter ring measures 1-1/4 wide x 1-1/2 long. The top cap is 3/32 thick and measures 3/4 wide x 2-1/8 long, with 1/4 holes on 1-1/2 center.
