Our series numbers are just a quick way to match bases & lids. Matching series numbers = matching products. e.g. Any 79 Series cup will fit any 79 Series lid
But how do we come to the specific series numbers? These are usually based on product width (e.g. 79 Series = 79mm rim, 185 Series = 185mm rim)
Series numbers help to easily determine lid fit, or even implement a universal lid fit system to aid your busy staff. Use cups from one series and you only need one lid to fit small, medium and large.
