These round metal clock dials are all American made. They have a 3/8" center hole and are measured from edge to edge. All of these dials are shipped with a protective plastic coating that needs to be removed before use.
We can produce custom metal clock dials for you, but the minimum quantity must be 100 pieces or more. We can also imprint a logo on existing dials in quantities of 50 pieces or more. Please contact an ISI sales representative for additional information.
