Overview

The nVent ASG4X4X3NK is a 4x4x3 inch Type 1 screw-cover enclosure constructed from 16-gauge galvanized steel, designed for indoor industrial and commercial applications requiring protection against falling dirt and accidental contact with live parts. This enclosure features a blank design with no knockouts, providing maximum flexibility for custom conduit entry configurations tailored to specific project requirements. Ideal for use as a junction box, pull box, or splice box, the ASG4X4X3NK offers a secure, tamper-resistant seal via its screw-cover design, ensuring reliable protection for wiring and electrical components in demanding environments. The galvanized steel construction delivers superior corrosion resistance, extending service life in potentially damp or corrosive settings while maintaining a professional appearance.
