The narrow 16" wide footprint of the 1616 Vasario cash drawers provides a compact foundation for smaller terminals and POS applications with space constraints. The 16.20" x 16.33" is a standard foundation size for electronic cash registers (ECRs). They are a great fit for small to mid-sized retail applications. The standard MultiPRO interface provides for easy configuration of these drawers to operate with popular receipt printers, ECRs and POS terminals.
