The metal housing in which much electronic equipment is contained provides suppression of radio frequency (RF) radiation generated within the housing. Covers which open but do not make a good continuous contact with the main housing, can result in a thin aperture along the front of a cover which acts as a wave guide or slot anything allowing electro-magnetic waves generated within the machine to be transmitted through such apertures or gaps. An RF radiation suppression clip can be used to give a mechanical join that divides the length of the aperture in half, so doubling the top frequency below which suppresion takes place. The mechanical join is effected using a spring-type finger that clips onto the front panel and presses against the top cover when it is fitted.
