The E14 threaded lamp holder in black bakelite with thermoplastic ferrules allows you to use a lampshade or any decorative element with a E14 fitting, regulating its high with the use of the two ferrules.
The black bakelite guarantees a very elegant “vintage look”.
N.B. This lamp holder has a security locking device that, in order to protect you from electrical shocks while you are changing the light bulbs, does not allow it to unscrew.
If the necessity to unscrew it should present, it is possible to unblock it by pointing at the security flap you will find at the base of the lamp holder with a screwdriver, while you are turning the lamp holder.
Always ensure the electricity is switched off when dealing with the bulb holder.
