Our Metal D-Rings with Squared Corners, at this time come only in two sizes, 3/4 inch and 1 inch. They are only available in light wire. The D-Rings are sized in relation to the width of webbing you are ordering. So, if you are ordering 3/4 inch D-Rings, you would need to order 3/4 inch webbing. If you would like, we can also powder coat your D-rings for a small additional charge. You can choose from 24 stock colors. There is no minimum on stock colors. You can also order from over 100 available colors. On custom colors there is a minimum of 150 pieces (you can combine different types of metal hardware to meet this requirement). Please keep in mind that powder coating can delay shipping your order, and that powder coating is only available with metal hardware. For more information on powder coating and your D-Rings see the powder coating page. There are hundreds of uses for these D-rings and these few head the list; belt buckles, dog collars, utility straps, etc. Here at Strapworks.com we have several types of D-rings such as; stainless steel, plastic, solid brass, and steel.
