The 300 Series gate entry systems are designed to mount on a “gooseneck pole” next to the driveway, or to be mounted on a wall with a rough stone finish. The 10 gauge steel housing (1/8″ thick) is metalized for rust prevention, and finished with a black texturized powder coat (electrostatically applied, and baked at 400 degrees). Models 304, and 305 include keypads in a variety of formats (ASCII, Crestron, Stand-alone, Wiegand).
