A rack (usually an effects rack standing next to or near to a mixing desk) has a removable front lid. The lid of the rack is to be used as a table top which can be set up next to the rack. A pair of folding legs are fitted inside the lid and a pair of 87988 studs to the opposite edge of the lid from the inside. Two round holes are made in the side of the rack and two 87987 mounting plates are fitted from the inside. The lid studs can now be clicked into the side of the rack. The studs will not release from the mounting plates without first being depressed.
