Printed circuit board or wiring panel apparatus includes a generally rectangular outer frame and a plurality of holding and receiving elements for holding and receiving the printed circuit boards or wiring panels. The holding and receiving elements include embodiments in which the side elements are permanently or pivotally secured to the sides of the rack frame and support elements secured to the bottom of the rack frame. One type of side receiving and holding elements may be curved and are generally parallel to each other for holding the boards or panels in a curved configuration during processing and transporting. Another type of holding and receiving elements may be pivotally connected for imposing a reverse curve in boards or panels. The rack apparatus may include frame elements which allow the frame to vary in size vertically and horizontally to accommodate different sized panels or boards.
