Legrand OFR89-4000 transition coupling

The Legrand OFR89-4000 is a black steel transition coupling designed for Series 4000 raceway systems. It connects OFR raceways with a height of 1/2 in and a width of 7 in, providing a single-channel pathway. The unit is ADA compliant and carries cETLus certification for safety compliance.

Screw-on mounting for raceway integration

This coupling mounts with screws directly onto compatible 4000 Series raceways, securing the transition between sections. It includes one removable divider that allows installers to separate cables within the single channel when needed. The steel construction protects wiring while fitting into the existing raceway footprint without additional clearance requirements.

Replaces worn or mismatched raceway joints

Installers use this coupling to replace damaged transitions or to join OFR raceways where a secure, code-compliant connection is required. The jump is worth it when the existing joint no longer maintains ADA compliance or when a steel-bodied fitting is specified for durability. It is not suited for raceway series outside the 4000 family or for multi-channel configurations beyond the single divider provided.
