Embodiments of the present disclosure are directed to a support assembly including a set of channel supports directly coupled to a channel member, wherein each of the set of channel supports may include an opening receiving a rotatable member. The rotatable member may extend between each of the set of channel supports. The support assembly may further include a set of beam supports directly coupled to a beam, wherein each of the set of beam supports may engage an upper surface of a flange of the beam. Each of the set of beam supports may include an opening receiving the rotatable member, wherein the rotatable member extends between each of the set of beam supports. In some embodiments, the set of channel supports and the set of beam supports are rotatable relative to one another about a central axis of rotation extending through the rotatable member.
