OptiMA® is proud to present our full line of quality American made, indoor glass enclosed bulletin boards and message centers. Locking glass enclosed message posting stations keep your messages safe and secure. Because the cabinets are locked you have control over what gets added to and deleted from the cabinets. We offer cabinets for indoor and outdoor use and yes there is a big difference in the way that the two are made. Outdoor cabinets require ventilation and drainage holes and use moisture resistant fabrics like vinyl. We have a complete line of outdoor enclosed bulletin boards too. All of our enclosed tack board cabinets come standard with natural tan cork tack surfaces or you can add a really nice colored fabric tack surface. Each unit comes standard with tamper resistant locks.
