Abstract

A sprinkler head is adjustably supported in three dimensions by an assembly including a first bracket having a cut-out and a second bracket having a cut-out. The first bracket has a circumferentially evenly spaced array of three threaded apertures around the cut-out. The second bracket has a similar set of unthreaded holes around its cut-out. Bolts extend through the second bracket and are threaded into the apertures of the first bracket. Nuts on the bolts may be used as stop elements. The second bracket is attached to fingers extending from the downcomer pipe to which the sprinkler head is attached. In a second embodiment, three fingers are provided, and they replace the second bracket. Adjustment of the sprinkler head about two orthogonal axes and along a third orthogonal axis parallel to the downcomer pipe can be achieved by turning the bolts from beneath the false ceiling through which the sprinkler head extends.
