This square block with brass centring pin is particularly well-suited to the creation of old-style luminaires.
It is cut from solid brass to give it an aged look, with a light brushed finish to hide any machining marks.
This square block is tapped through to allow an electriccable to pass through, and the M10 internal thread accommodates M10 tubes for the installation of a bulb socket, ceiling lantern or rose.
