These 'T' light holders are fitted with a strong circular magnet in the stem which connects to a steel disc on the glass holder. This enables the glass holder to be easily removed and cleaned when necessary. This also means that the holders may be mixed/matched.
Many of the stems are from copper pipe which has been polished and then sprayed with a clear lacquer to prevent tarnishing. The recycled wooden bases come in a variety of shapes and sizes and finishes, all with felt pads to prevent scratching of surfaces.
