ABSTRACT:
A fire protection sprinkler head arrangement comprises a flange attached to a bracket on the sprinkler body by boss and shoulder joints, e.g., bayonet joints. The flange serves as a brace preventing sagging of ceiling tile and unwanted retraction of the sprinkler head rearwardly with respect to the ceiling or a sidewall. One embodiment of the flange is adjustable axially relative to the sprinkler body by an upwardly directed series of shoulder joints into which the boss is selectively fitted to conform to a particular ceiling or wall structure and feeder pipe system.
