Abstract: A support rack, such as for supporting automobile body parts during painting, may be supported entirely from overhead by a single vertical support tube received within an overhead mounting bracket. A central frame has a sidewardly projecting cross member, which supports side members which extend front to back. A front frame projects frontwardly of the cross member, and has adjustable side support arms. When a fender is supported on one of the side members by an upper edge, one of the side support arms can be adjusted to properly engage the fender. Alternatively, the rack's vertical mount tube can be supported from below on a wheeled support frame. Adjustable pin collars can be moved along the side arm to support parts which have mounting holes.
