Abstract
A rack for hanging workpieces in industrial coating systems having a horizontal bar or beam with an upper flange, a lower flange, and a web joining those flanges, wherein the upper flange has a hook receiving aperture, and the flow flange has a hook receiving slot. The aperture and the slot are aligned to receive a hook from which a workpiece may be hung. The hook is bent near its upper end to form a spring with a terminal leg and a depending leg. The end of the terminal leg extends into the aperture in the upper flange, and the depending leg extends through the slot in the lower flange, behind a detent. The force of the spring biases the depending leg against release from behind the detent.
