Abstract: Apparatus for securely retaining hangers includes a hanger bar, a retainer bar, and a pair of end assemblies. Each end assembly is coupled to an end of the hanger bar and has a pair of guide walls projecting away from the hanger bar to form a guide channel. The retainer bar is slideably disposed and moveable within the guide channel between an open position and a clamping position to engage and secure the hangers to the hanger bar. A latching mechanism is attached to each end assembly and is engageable with the retainer bar to secure the retainer bar in the clamping position. The latching mechanism is preferably at least partially disposed between the guide walls to protect the latching mechanism from accidental bumping, thereby reducing unintentional disengagement of the latching mechanism. The apparatus can include at least one biasing member that urges the retainer bar away from the hanger bar to facilitate loading or unloading of the hanger bar.
