This is a quality wire frame in an unusual pretty scalloped flower bell shape for making a pleated/gathered or tailored soft bodied lampshade.
Base diameter 16” at narrowest point and 16 3/4” at the scallops
Slope height 10”
Top diameter 8”
The final photo is an example I have made with this style of frame (in a larger size).
Duplex ring fitting ( for use with a shade carrier which is available to purchase separately).
