4000® Series Raceway is the work horse of surface raceway systems. 4000 Series Raceway can be divided for multi-service applications making it ideal for applications requiring a large cable capacity and dual-service requirements. Commercial, institutional, and industrial applications benefit from the rigid steel construction and durable ScuffCoat™ finish of this raceway. 4000 Series Raceway is also ideal for municipalities that have code requirements calling for all steel construction or that prohibit nonmetallic cable management systems.
