Display important messages and announcements in Best-Rite's Outdoor/Indoor Enclosed Bulletin Board with Two Doors. Insulation board backing supports the self-healing natural cork surface, and the anodized aluminum frame is sure to blend nicely with your décor. Lockable acrylic doors keep information safe from theft and vandalism. For indoor or outdoor use; outdoor boards should be used beneath an overhang or in a semi-enclosed space. Choose from two frame styles and a number of sizes.
