The CP4 Cover Plate, part of a full family of canopies from Auroralight, is an architectural upgrade worthy of consideration. The CP4 is compatible with many box sizes and utilizes a STANDARD: 1⁄2” (NPS) Universal Thread for near limitless fixture compatibility. The CP4 is machined from solid brass for durability; the traditional look complements any décor while concealing the screws in an elegant solution.
