An edge mask for a printed circuit board comprises a Tsectioned strip, to the base web of which can be secured a printed circuit board, via lugs and screws. The strip carries a handle at each end pivoted on a respective shaft having side walls which pass through a slot and cut-away and end in hooks which engage a subframe member of apparatus in which the board is assembled. The handles can occupy alternative retaining and pulling out positions, and are biased by respective springs into the retaining position. Contact strips are also provided for effecting an earth connection to the apparatus frame. |
