Overview

The nVent ADSTOPK Door Stop Kit (SKU: ADSTOPK) is a precision-engineered steel solution designed to secure Type 4 and Type 12 Hoffman enclosures with horizontal-opening doors and a 'B' dimension of 16.00 inches (406 mm) or greater in the open position. This US-made kit prevents accidental door closure, protecting sensitive equipment during maintenance, inspection, or servicing operations. Constructed from durable plated steel, the ADSTOPK resists wear and corrosion, making it suitable for harsh industrial environments including manufacturing, automation, and control systems. Installation requires drilling two small holes in the enclosure body and two in the door, followed by mounting the stop arm at the top or bottom of the door opening. The stop arm’s angle is adjustable via a wingnut, and it slides neatly out of the way when the door is closed. The kit maintains UL/CSA Type 4 and Type 12 ratings when properly installed in Hoffman enclosures. Compatible with left- or right-hinged doors, the ADSTOPK is not intended for CONCEPT window door enclosures, swing-out panels, or swing-out rack frames. Typical applications include securing control panels in industrial automation systems, protecting electronics in manufacturing environments, and maintaining access in data centers or telecom facilities.
  • Can be mounted at the top or bottom of the door opening
  • The angle of the door is easily adjusted by means of a wingnut
  • The stop arm slides neatly out of the way when the door is closed
  • Maintains UL/CSA Type 4, 4X, and 12 if properly installed in HOFFMAN enclosures
  • Stainless steel mounting screws and nylon washers are included
