A pin locking apparatus for use in a support fixture includes a locking plate (10) having a pin receiving hole (12) and a ball receiving hole (14), and a ball (16) contained within the ball receiving hole. The bottom of the ball receiving hole (14) merges with a lower portion of the pin receiving hole (12). In a locking position, the ball (16) of the pin locking apparatus is positioned approximately at a bottom of the ball receiving hole (14), and in an unlocking position, the ball (16) is remote from the bottom of the ball receiving hole (14). The pin locking plate (10) may be included in individual pin locking modules (100), which may be added, rearranged or removed from a supporting device (130). The pin locking plate (10) may also be included in a supporting device (130) wherein the pins (18a) are locked and unlocked using vacuum and air pressure, and in a supporting device (130) wherein the pins (18a) are locked and unlocked manually by twisting, lifting and lowering the pins (18a).
