Hettich HCS 400 with Hold-Open Slide Rail (EN 2-4) - Concealed Door Closer

Overview

The Hettich HCS 400 is a concealed (invisible) door closer designed for heavy commercial and residential doors. It uses a CAM action mechanism and a hold-open slide rail, allowing the door to stay open at a set position when needed. Because the closer body is hidden within the door and frame, it preserves a clean architectural line while still delivering controlled, silent closing.

It is EN1154 certified, fire rated, and tested for 500,000 operating cycles, making it suitable for fire-rated door assemblies and high-traffic entryways where reliability and code compliance matter.
