The first and second conduit members each have an inlet portion and an outlet portion that are offset relative to each other by a predetermined distance. The sprinkler head is positionable anywhere within a circle having a radius equal to the sum of the offsetting distances between the inlet and outlet portions of each conduit member. Elbow couplings further increase versatility. The elbow couplings may have an inlet positioned at a 45° angle or a 90° angle relative to an outlet.A drop line fitting is weldable to a sprinkler drop line and includes a socket for receiving sprinkler system plumbing such as the first and second conduit members.A drop line fitting is releasably secured to a sprinkler pipeline and includes either a socket for receiving sprinkler system plumbing such as the first conduit member or includes a portion having a smooth outer circumferential surface to be received by a socket of sprinkler system plumbing such as the first conduit member.Other References
