Strapworks carries nickel plated Metal Opening O-Rings (sometimes called 'Binder Rings'), in three different sizes: 1 inch, 2 inch, and 3 inch. The metal opening O-rings are sized according to the inside dimensions. For more information, please click on the RED technical specs tab above.
We can also powder coat your Metal Opening O-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 metal opening O-rings, please see the Hardware Colors page. When viewing the metal hardware colors page, please scroll down to the bottom of the page to read important information on powder coating.
	Metal opening O-rings are most often found on school notebooks. However, those rings are also typically spring loaded. Strapworks' metal opening O-rings are not spring loaded and work great as key rings, mobile Rolodex flippers, quick release connectors between runs of webbing. Other uses include: swatch books, carpet sample books, color reference charts, and display hanging rings.
