This system will convert a lampshade that has a Duplex Shade Ring Fitting (centre hole size 110mm) to work with Harp & Finial Systems.

This is a three part system comprising of

  • Spider Fitting - Lamp Shade Duplex Adaptor
  • E27/E26 to B22/E14 Lampshade Reducer / Converter Adapter
  • Converting Washers

Shades that use this system have many advantages over fixed fitted frames.
The lampshade can easily be lifted off without undoing the Finial to Change, Clean or Replace the bulb.

Converting instructions -

  1. Squeeze the Adapter and install into the centre of the Spider fitting to reduce the aperture.
  2. Insert a Converting Washer onto the stem of the Harp System.
  3. Place your Spider fitting onto the thread of the Harp System, with the legs facing upwards.ensuring the Converting Washer fits into the ridge of the Adapter.
  4. Place the other Converting Washer on top of the Adapter, fit into the ridge, and then screw on your Finial and tighten.
  5. Place your lampshade over the spider, allowing the legs to cradle the Duplex Ring
  6. Your lampshade can now be used.
