RING METAL CAPCITY REMINDER

The capacity of a ring, memo, or visible record metal is the inside diameter of the arches (rings). While the trade traditionally refers to ring capacitates as: 1 inch, 1-1/2 inch, etc. the inside measurements are approximately equal to or up to 1/8” greater than capacity.
