A modular sprinkler assembly includes a sprinkler body having an annular cap supporting ring and a nozzle for emitting a liquid stream to atmosphere. A cap assembly is removably secured to the cap supporting ring, the cap assembly including a stream distributor. The cap is formed with a top wall and an annular depending skirt, an interior surface of the skirt having at least one latch device formed thereon. The latch device includes a wedge-shaped surface portion and a land portion, and the cap supporting ring has at least one radially extending tab adapted to ride on the wedge-shaped surface portion and to seat on the land portion upon rotation of the cap relative to the sprinkler body. The cap assembly may support a pair of differently configured stream distributors facing in opposite directions, and in this cap construction, the cap is reversible, i.e., the cap can be inverted and reattached to the sprinkler body to take advantage of the additional stream distributor.
