The Wiremold 880MPA is a single-gang non-metallic adjusting ring designed for use with the Modulink 880MP floor box system and includes a fiber storage loop, brass inserts for secure flange connection, a green ground wire, and mounting screws for easy installation. It provides full adjustability post-pour, allowing installers to fine-tune the floor-box flange height for tile, carpet or concrete finishes, streamlining installation and reducing costly rework. The ring is crafted from durable PVC material, measures approximately 4.0″ wide × 1.5″ high × 5.38″ deep, and is cULus listed and RoHS compliant for use in commercial spaces. Adaptable to the Wiremold CM Series open system inserts that snap directly into the ring without additional adapters, it gives versatile support for power, data and communications services from a single floor box platform. Ideal for office floors, retail interiors and multi-use commercial buildings where aesthetics, flexibility and code compliance matter.
