G.P.O. Insulator, No. 10

This side knob insulator is used at the top of an arrangement to bring a pair of open wires down a high building to a lower point where they can terminate on the lead-in cable at a convenient height for fault finding. The lower point uses pot head insulators with side knobs

Unfortunately the lower specimens and their bracket have been painted to match the surrounding woodwork.
