Cork bulletin boards are a standard for display, but when you have a busy or high traffic space an enclosed cork bulletin board is a better choice. It is easy to pin items into the natural cork surface, and because they are protected behind a safety glass door it is very unlikely that they will fall or get damaged. Two sliding doors move over each other so that you can easily change out your signage at any time. While on display, the door can be locked for maximum security and protection. Two keys are included. The display space measures 53"W x 37"H and holds up to 18 sheets of letter size paper.
