A hook assembly includes a substrate having three tabs arranged in a triangular configuration, a hook including a pair of opposing side flaps, and a tripod mounting member configured to couple the hook to the substrate. The tripod mounting member includes three legs arranged in a triangular configuration, a pair of opposing side plates extending from two rear legs of the three legs, and a stopper groove. The three legs of the tripod mounting member correspond to the three tabs of the substrate. The hook assembly also includes a torsion spring having a pair of arms extending from opposite ends of the torsion spring, a first fastener configured to couple the tripod mounting member to the substrate, and a second fastener configured to extend through the side plates of the tripod mounting member and the side flaps of the hook to rotatably couple the hook to the tripod mounting member.
