Abstract: A light fixture mounting system including a nipple assembly configured to be secured relative to a structure. The nipple assembly includes a longitudinally extending nipple with at least one longitudinal channel and a series of outer threads. A fixture mount assembly includes a mount body, a prong assembly extending from the mount body and including at least one prong leg extending to a free end with an outwardly extending prong foot, and an adjusting nut positioned about the at least one prong leg between the mount body and the respective prong foot. The fixture mount assembly is positioned relative to the nipple assembly such that each prong leg is positioned in a longitudinal channel and the adjusting nut is positioned such that the adjusting nut contacts the at least one prong foot and the at least one prong leg is retained in the corresponding longitudinal channel.
