Overview

The nVent Hoffman A4424RT is a NEMA Type 3R-rated wiring trough designed for outdoor wire and cable protection in wet conditions. Constructed from 16-gauge galvanized steel with a gray finish, this 4.00" x 4.00" x 24.00" trough provides reliable defense against moisture, rain, sleet, and snow. Its drip-shield top and seam-free sides prevent water ingress while the removable cover allows easy access for installation and maintenance. The hinged cover design enables quick access, and the screw-fastened closure ensures security against unauthorized entry. Compatible with a Padlock Hasp Kit (sold separately), it supports controlled access in high-risk environments. The trough features embossed mounting holes on the back for straightforward installation and integrates seamlessly into larger electrical systems. With a 4" x 4" internal dimension, it offers ample space for branching, splicing, and terminating cables. Ideal for commercial, industrial, and utility applications, including substations, telecom shelters, water treatment facilities, and manufacturing plants.
