Abstract
An indicator post for indicating an open or closed condition of a valve in a piping system has a post which has a rotatable operating nut at the top of a post head. The post head is attached on its lower end to an upper barrel having a telescoping lower barrel within it. The operating nut is also attached to a solid upper stem. A hollow lower stem surrounds the lower end of the solid stem and has a lower end attached to a valve assembly socket for mating with a valve stem. The hollow stem is freely slidable along a large portion of the solid stem so that the assembly may accommodate a large range of valve stem-to-operating nut distances. The operating nut carries a threaded sleeve which is preferably constructed of molded, engineering-grade plastic.
