M³ Showcase Lock

The Medeco® Showcase Lock is specifically designed for installation on sliding cabinet door applications that require extra protection beyond what ordinary showcase locks provide. Complete with a solid steel locking bar and anti-spread housing, the Medeco® Showcase Lock is ideal for securing showcases and cabinets where two sliding surfaces are to be locked. No other lock can be compared with Medeco's proven track record of security and long term reliability. Patented key programs prevent the unauthorized duplication of keys and maintain system integrity. Keyed alike, keyed different, or master keyed, the Medeco® Showcase Lock is the perfect solution for your showcase security needs.
