40cm Duplex Top Circular Lampshade Ring – ShadeCore ® Our 40 cm Duplex rings are a versatile and practical choice for a wide range of lampshade designs. They are commonly used in tapered styles, including Conical and Empire shades, as well as circular Drum shades. Designed to work with different types of lighting, a Duplex lampshade can be paired with a Shade Carrier for table and floor lamps or used with a Spider fitting for pendant lights. This flexible system allows the lampshade to be lifted off the fitting without dismantling the lamp, making it easy to remove for cleaning or swap for a different shade whenever you would like to refresh your décor. ✔ Manufactured for Makers ✔ Trusted by Professionals ✔ Strong 3.25mm Steel Wire ✔ Epoxy Coated White Finish ✔ Compatible with UK, EU Fittings Each Duplex unit consists of two rings. The larger upper ring forms and supports the top diameter of the lampshade, while the smaller 110mm lower ring sits securely on top of the chosen Shade Carrier or Spider fitting. Together, the two rings provide a stable internal framework while retaining the convenience and versatility for which Duplex fittings are known. The frame is at the heart of every lampshade design. It defines the shape and supports the structure. You can rely on ShadeCore® frames for strength, accuracy, and professional results every time.
