An improved cap and assembly is provided for a poured concrete deck. The improved assembly has a diaphragm seal over-molded to a top plate having a depending sidewall that is snap-fit to a base containing a fire ring. A tubular sleeve is connected to the over-molded top plate by snap fit connections to the sidewall and by threaded fasteners passing through sockets in the sleeve, sidewall and base. The over-molded diaphragm has a funnel shape. A first sleeve cap has depending positioning tabs that may be broken off to adjust the cap height relative to the sleeve, with an inwardly extending latching surface engaging the sleeve when the tabs are removed. A second cap has inwardly extending tabs that fit into channels on the sleeve fit between ridges on the sleeve when rotated to adjustably position the second cap on the sleeve.
