Overview

The nVent Screw-Cover Pull Box Extender Type 1 (SKU: A16124SUG) is a galvanized steel solution designed to expand wiring capacity in commercial and general industrial pull box installations without the need for costly custom fabrication. This versatile extender, part of nVent's industry-leading Type 1 enclosure system, transforms existing pull boxes into larger enclosures by simply sliding onto the main box using standard hole patterns and hardware, eliminating the time and expense of ordering custom-sized units. Engineered for UL 50/50E and cUL Listed compliance with NEMA Type 1 and IP30 ratings, the extender maintains critical grounding continuity between the main enclosure and extension while providing ANSI 61 gray powder-coated protection or durable galvanized finish options.
