The N Plug To F Socket Adaptor is offered by us that fits perfectly into a type F socket. The socket is recessed by 15 mm, so partially inserted plugs do not present a shock hazard. Socket adapters are used to adapt the drive size of a socket for use with a wrench with a different drive size. For example, a N Plug To F Socket Adaptor can be used to adapt a socket with a 1/4" square drive for use with a wrench with a 3/8" square drive.
