A face plate which attaches to a printed circuit board or blank board for insertion and removal of the board from the chassis and limiting EMI emission while allowing connector and indicator accessibility. The face plate has an elongated frame having at least two planar body portions. The planar body portions are integrally formed to each other with the planes of the two planar body portions at an angle of between 25 and 55 degrees of each other. The elongated frame has a pair of free edges adjacent to the planar surfaces and the pair of side edges. The face plate has a pair of mounting devices. Each mounting device is carried by the elongated frame in proximity to one of the free edges.
