Linear ACCESS® logo at top. A driver in a vehicle reaches toward an access-control device mounted on a dark curved mounting post. An inset photograph shows the mounting faceplate and curved post arm attached beside a vehicle. The post is shown mounted on a concrete curb/base. No dimensions, part numbers, torque specifications, wire specifications, or step order are shown. ## Page 2 For the easy installation of keypads, telephone entry systems, and other access control products and for the convenient use of these devices from a vehicle, Linear offers two types of well-built mounting posts. The GNC-1 is a curb mount model that includes a base plate with extra large 5/8-inch holes to accommodate lag bolts to anchor the post directly and securely to concrete. As an alternative, the GNB-1 is a burial mount for installations where a curb mount is not practical or desired. The material for both mounting posts is 2-inch by 2-inch, 1/8-inch thick, cold rolled steel. A powder coated finish and mounting flange gasket makes these posts extremely weather resistant. > Figure: Product renderings of two curved mounting posts. Left post is labeled “Burial Mount Model GNB-1” and extends into a concrete block. Right post is labeled “Curb Mount Model GNC-1” and is attached to a square baseplate on a surface. Both have a mounting flange/faceplate at the end of the curved arm. > Figure: Photograph labeled “Mounting Flange for both Models.” It shows the curved post arm with a square mounting flange and a separate gasket/flange plate with a large center opening and four corner mounting holes.
