Abstract: A rotating bracket includes an endcap, a fastener, a support, a spacer, and securement structure. The endcap is adapted to fit an end of a linear lighting channel and has a keyed opening. The fastener has a keyed shank complementary to the keyed opening of the endcap and is adapted to be inserted into the endcap with the keyed shank of the fastener engaging the keyed opening of the endcap. The support has a slot or opening adapted to accommodate the fastener. The spacer is adapted to insert over the fastener such that it is positioned between the endcap and an inner face of the support. The securement structure engages the end of the fastener beyond an outer face of the support. Linear luminaires using the rotating bracket are also disclosed.
