The Q-2100R mold library is a self contained two drawer storage system. The system separates the front molds and back molds for quick and easy access. Each mold drawer contains metal trays with alpha numeric dividers for each individual mold. Simply dial the Rx into the Q-2100R and the computer will select the correct front mold, back mold and gasket for each lens. The operator can then easily find the correct mold family and select the correct numbered mold for that Rx.
