Enclosed Vinyl Bulletin Board is the perfect way to display messages, pictures and important information securely. Vinyl tack surface hides pinholes and holds up under repeated tacking, providing years of reliable service. Board will not break down or mold unlike cork enclosed boards when used outside. Hang it under an awning or overhang to avoid damage from weather or humidity. Enclosed bulletin board is protected using shatterproof acrylic panels, full-length door hinges and locks that are flush with the frame. Install it in high-traffic public areas without worrying about damage or tampering. Hidden corner brackets let the message center sit flush against the wall with no visible hardware for added protection against vandalism. Colored vinyl surface complements the aluminum frame. Board includes two keys. It's perfect for indoor and outdoor use.
