A plurality of guides facilitate linear translation of the carriage on the vertical structure without marring. At least one hook on the carriage pivots to engage a slot on the support structure for locking the carriage in a raised position. Objects are attached to a flange on the carriage. A winch and cable control motion of the carriage.
