Lathem' s 25-Pocket Expanding Time Card Rack holds any standard time card (up to 23cm long and 10cm wide). This rack expands for easy wall mounting and can be combined with others. Excess pockets can be removed to fit your company size. The durable black plastic construction resists damage and maintains an attractive appearance in even the harshest environments. Includes pocket number labels and mounting hardware. Many companies use two racks; one on each side of the clock. As employees clock in, they move their card from the "out" rack to the "in" rack. This allows managers and supervisors a quick visual determination of who has clocked in. Since 1919, Lathem' s singular focus has been to manufacture innovative, durable and affordable employee time and attendance systems.
