ABSTRACT:
A sprinkler head guard includes an inner casing that has a cylindrical shape, and vertically aligned top and bottom openings. A first coupling is conjoined to the inner casing and has a threaded inner surface. A second coupling has axially offset lower and upper ends having threaded outer surfaces. The upper end is mated with the first coupling. The lower end is mateable to a water supply line. An outer casing is slidably and telescopically engageable with the inner casing, and has a bore that becomes situated about the first coupling. The outer casing has a top lip that is flanged outwardly and includes rectilinear creases formed therein. Each crease defines a line of weakness, allowing a user to snap off a top lip portion. The inner and outer casings are shaped for housing a sprinkler head therein. A mechanism is included for locking the casings together.
