ABSTRACT:
In the particular embodiments described in the specification, a sprinkler guard is formed from eight U-shaped wire members arranged uniformly about a sprinkler axis and joined at one end to a ring and at the other end to two opposed base plates which each receive four of the U-shaped members, leaving an opening through which a conventional sprinkler head can be inserted into the guard. The base plates have downwardly projecting portions with opposed surfaces to engage flat outwardly facing surfaces on the conventional sprinkler head and also have outwardly facing surfaces for receiving a wrench to mount the sprinkler head after the guard has been assembled on it.
