Simplex locks have been the industry standard for decades. Mechanical pushbutton locks are a great solution for controlling access between public and private areas while allowing free egress. This type of lock is ideal for access points, such as a front/back door, restroom, lab, office door, storage room, and common door. Simplex locks supplement other security access systems or operate as stand-alone security solutions and provide a durable, reliable choice for multiple markets and applications.
