Overview

The nVent ASE20X14X3NK is a Type 1 NEMA-rated steel screw-cover enclosure designed for junction and pull box applications in commercial and general industrial environments. This 20x14x3 inch enclosure (SKU: ASE20X14X3NK) provides reliable protection against falling dirt and accidental contact with a durable 16-gauge steel construction and ANSI 61 gray polyester powder paint finish. Unlike models with pre-drilled knockouts, the solid enclosure face allows for custom conduit entry configurations, minimizing ingress points and optimizing cable routing. The screw-cover design ensures secure closure and easy access for maintenance while the embossed mounting holes on the back enable straightforward installation. Ideal for housing electrical connections, wiring splices, and conduit runs, this enclosure meets UL 50/50E and cUL Type 1 requirements (File No. E27525). Its compact 20x14x3 dimensions offer ample internal space for wiring management in flush or surface-mounted installations. Compatible with nVent's flush cover and door frame accessories for extended versatility.
