Abstract: A rack assembly has a brace bar with first and second opposing end portions. The first end portion terminates in a crossbar comprised of a first arm opposite a second arm. The first arm is fixed between the brace bar and a shaft. A sleeve receives the shaft, with at least one of the shaft and the sleeve pivoting relative to the other about a pivot axis. The brace bar is rotatable about the pivot axis with the crossbar fixed thereto. A slot connector includes a body fixed to the sleeve, and a catch pivotally coupled to the body. The body defines a first notch opposite a second notch, both of which are opposite the sleeve. The connector is structured to selectively engage/release a slot, and the notches are structured to receive opposing edges about the slot when the connector engages the slot.
