This clip is a custom made item that we have created to turn our pleated Danish lamp shades in to pendant light fittings.
Just clip one of these on to the Danish shade, and it can be attached to an E27 Edison Screw fitting (40mm in diameter).
Please note - if you are purchasing a shade the cost of a stand is free. We will give the purchase price and shipping discount of $29.70 as a discount when you select the 'I am buying a lampshade too' option.
