Abstract
Abstract A retrofit sprinkler system is installed into existing structures by means of a bracket which is mounted on the existing walls adjacent the ceiling to support flexible sprinkler pipe and related utilities. The bracket has a wall-mounting flange, front and bottom flanges for mounting a facade and soffit, and a central support opening. The support opening may be a closed circle or an open J-shape. In one embodiment the front flange may be adjustable toward and away from the existing wall to correct for irregularities in the existing wall.
