A wall-mountable hanger bracket assembly includes a main frame, a plurality of horizontal beams, a plurality of first coupling members, a plurality of releasable securing members, a plurality of pairs of bracket members for receiving and supporting an article thereon, and a plurality of second coupling members. The main frame is securable to a wall. The horizontal beams are disposed between a pair of opposite upright side members of the main frame. The first coupling members slidably attach the horizontal beams to the upright side members of the main frame. The releasable securing members hold the first coupling members in place on the upright side members of the main frame. The second coupling members slidably and pivotably attach the bracket members to the horizontal beams. The bracket members vary in length with the shortest being at the level of the uppermost one of the horizontal beams and longest being at the level of the lowermost one of the horizontal beams.
