<p>Of THE DISCLOSURE An indicator post is disclosed for an underground valve or a valve within a building. The indicator post is an improvement over existing units because it has panoramic windows allowing viewing from almost 360.degree. around the post and includes readily positionable targets for different types of valves. The indicator post has a detachable cap mounted on an outer casing, a rotatable stem member in the casing adapted to be converted to an operating stem of the valve, at least two curved viewing ports extending in a single curve around the cap, a curved target carrier within the cap, at least one flexible target strip having a valve position indication thereon, adapted to be wrapped about a portion of an outer surface of the target carrier and visible through the viewing ports for almost 360.degree. around the post. Fastening means are also provided extending over at least a portion of the axial length of the target carrier for fastening the strip anywhere along the portion of the axial length of the target carrier, and means for moving the target carrier past the viewing ports when the stem member is rotated to operate the valve thus moving the target strip to or from the viewing ports.</p> |
