Eaton 4424 GRT Wiring Trough - NEMA 3R, 16 ga Steel
Part Number: 4424 GRT
Quick Summary
Eaton B-Line series wiring trough is a durable channel designed to organize power and control wiring in enclosure installations across manufacturing floors. This 4424 GRT model provides a 4 in by 4 in by 24 in footprint with a 16 gauge steel body and ANSI 61 gray finish, delivering both protection and accessibility. If you’re wrestling with crowded panels, embossed thru holes and multiple knockouts simplify mounting and routing while keeping cable runs tidy. The trough is CSA Certified and UL Listed, with NEMA 3R enclosure protection that withstands indoor exposure and incidental rain. For integrators and maintenance teams, the combination of robust metal, secure screw covers, and flange-mounted closure reduces field adjustments and downtime while improving standardization across facilities. In practice, this aligns with procurement goals for reliable, scalable wiring infrastructure and long-term cost of ownership.
