Marinco CDFF-E CLS Cam-Type Coupler 400A Female-Female Green 1/2″

Description

Product Overview

The Marinco CDFF-E CLS cam-type coupler is engineered for demanding electrical installations where reliability and durability are paramount. Constructed from solid weatherproof rubber, this coupler is UL and CSA listed, meeting NEMA 3R and NEMA 4 standards for wet locations. Its 1/2 inch NPT thread size ensures a tight, leak‑free seal, while the green color provides easy visual identification on crowded panels. The non‑conductive retaining screw passes through the metal contact and fastens at both ends, delivering maximum resistance to excessive torque loading and preventing accidental disengagement.

Usage

Designed for a wide range of outdoor and marine applications, this coupler excels in environments exposed to rain, splashing, and occasional submersion. It is ideal for connecting generators, marine engines, outdoor lighting circuits, and industrial control panels that require a robust 400 A rating. Electricians and maintenance technicians will appreciate the ease of installation—simply thread the coupler onto compatible cam‑type connectors and tighten the retaining screw to achieve a secure, torque‑resistant joint. The coupler’s compact dimensions (6.1 x 1.7 x 0.1 inches) allow it to fit into tight panel spaces without compromising performance.
