3/8" Flex/AC Cable Set-Screw Connector

Raco 2511 – 3/8" Set-Screw Connector for Armored and Metal-Clad Cable

The Raco 2511 is a 3/8" set-screw connector designed for terminating Type AC (armored cable) and MC (metal-clad) cables to electrical boxes and enclosures. Constructed from precision-cast zinc, this connector delivers dependable mechanical retention and grounding continuity in accordance with applicable code requirements.

Its compact profile and fixed-body design support secure and efficient cable entries in new construction, retrofit, and commercial electrical distribution systems. The set-screw mechanism allows for reliable fastening under load, minimizing cable movement and strain at the termination point.
