A perforated board display bracket assembly is adapted for mounting on a perforated board. The perforated board openings receive a hanger member comprised of a flexible U-shaped rod having generally parallel spaced legs connected by a crown. The legs are retained against the back side of a display panel by a locking bar which engages the legs and biases the legs toward the panel. The display panel may slide on the legs between a locked and unlocked position. When in the locked position, the hanger member is in a detent. Manual flexing of the legs releases the hanger member from the detent and permits sliding of the display panel on the hanger member for ultimate removal from the perforated board.
