ABSTRACT:
An improved post support for a valve position indicator of an underground valve. The post support includes two telescoping sleeves of which one sleeve is provided with two sets of a plurality of aligned equispaced openings located in 180.degree. angularly spaced relationship. The sets of opens are lengthwise of set so that the centers of the openings of one set lie midway between the centers of the other set. The other sleeve is provided with 180.degree. angularly spaced openings linearly spaced a distance equal to one half the spacing between the openings of the two sets. Relative rotation of the telescoping sleeves and length displacement permits an adjustment of the length equal to the linear spacing of fastening means.
