Abstract: A gang channel nut assembly permits nut plates held therein to be used even though the assembly channel is in contact with a stringer. The instant invention enlarges the fastener hole in the channel as well as slots on both sides of the channel and cuts a connecting slot between the hole and the slot sufficient to permit passage of a fastening screw or bolt. In this way the gang channel nut assembly still functions as originally intended that is, to positively retain the nut plates and align them in the channel, but permit the nut plates to be flexible or float transverse of the channel without falling out of the channel.

Abstract: A mounting structure including a locking plate disposed between a mount and a frame structure is described. The locking plate is provided with a central locking hole.
