Create important messages or announcements that need to be outdoors with our Outdoor Plus Enclosed Letterboards with Traditional aluminum frames. PLUS refers to the additional protection built into each of our Outdoor boards. Each cabinet door is lined with weather seal and has dual locks. Vent holes and drain holes are in the bottom and sides of each cabinet, for airflow. A drip edge is mounted on the face of the cabinet, so rain runs off the front of the cabinet instead of down the acrylic window. Mitered corners stay dry from sealant applied in our factory. Proprietary synthetic tack, moisture resistant and fabric covered backer board is utilized in case dampness cheats its way into one of these cabinets; it will not wick. The traditional design of the frame also alerts those passing by that the board contains crucial information, giving direction to the public. Inserting the letters is an effortless and quick experience, since our boards are carefully crafted with precise felt grooves that keep letters in place. Due to its durability, Outdoor Enclosed Letterboards are able to withstand use in high traffic areas, increasing successful results by making sure announcements will be seen by larger crowds.
