A rack for hanging workpieces in industrial coating systems having a horizontal bar or beam with a first flange, a second flange, and a web joining those flanges, wherein the first flange has a hook receiving aperture and the second 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 to form a spring having a terminal leg and a depending leg. The terminal leg extends into the aperture in the first flange and the depending leg extends through the slot in the second flange, behind a detent. The web is formed so as to providee a fulcrum against which the spring bears, biasing the depending leg against release from behind the detent.
