Comfort Fit

The comfort fit designation applies to rings in which the insides are
convex, and not flat. There is no standard measurement, as each
manufacturer designs to his partuicular specs. We, at Hoover &
Strong, just came out with “EZ” Fit wire which we sell in minimum 6
inch lengths. Available in all metals, our measurements are 3, 4 and
5mm wide and all are 2mm thick.
