A concealed frame-type automatic sprinkler with adjustable cover is provided by a sprinkler with a sprinkler body, an outlet on one side of the sprinkler body, a frame which extends from the body completely around the outlet, a plug retained in the outlet by a heat-sensitive element, and a pair of spring clips retained on the sprinkler by an adjustment screw passed through the frame to preload the heat-responsive element against the plug. The clip members are diametrically opposed and extend radially outwardly on either side of the frame. Each includes a pair of arms with tabs sized and positioned to engage with ribs provided on an inner cylindrical surface to a central cylindrical bracket member provided on an inner side of the cover. A gauge bracket may be mounted on the sprinkler to assure a deflector of the sprinkler is located at a proper height with respect to the ceiling through which the sprinkler extends.
