3 x quality rubber cable grommets ideal for re-wiring or restoring Vintage Herbert Terry 1227 Anglepoise Lamps, where cables of up to approximately 6mm in diameter are used.  

These work very well with 2 and 3 core 0.6mm² braided twisted cables and many other cables up to around 6mm in diameter. 

Grommets are necessary to prevent damage to the cable as it passes through the sharp punched hole in the anglepoise arms and should be replaced during rewiring.
