Ensure vital equipment cannot be accessed by locking off the socket at the wall outlet. This lockout is suitable for standard UK single sockets, and can be used for switches, power sockets, network points etc. To fit, isolate the power to the outlet, loosen the screws and place the cover behind the faceplate. Re-tighten the screws pulling the cover into place. Please note that the cable gaps are located at the side and may not be suitable for thicker/rigid cables. To use cover with plug sockets, turn the cover 90 degrees. Up to two padlocks can be fitted integrally to the unit.
