发明名称 Sprinkler head location indicator
摘要 The sprinkler head location indicator is a shallow dish adapted for placement on the shaft of a pop-up sprinkler head. The dish is concave upward and has a small pilot hole formed through its center. A plurality of radially extending guidelines is formed on the bottom surface of the dish, the guidelines having hash marks at uniform intervals to form scale markings. The guidelines are severed radially to a uniform length forming flexible segments and the dish is pushed up the shaft to the ground flange of the sprinkler head. The flexible segments bend against the sprinkler head shaft, thereby retaining the dish on the shaft.
