We print this ring on demand using the design from ProtoX3D. It fits E27 socket lamps and works with most standard lampshades that use a 40mm thread. If your vintage lamp lost its ring or yours cracked with age, this replacement gets you back to beautiful working light without the cost of a new lamp.
