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.
What It Does
- Closes doors smoothly and silently after use, with an adjustable closing and latching speed.
- Holds the door open at a selected position via the EN 2-4 hold-open slide rail.
- Operates through a door opening angle of up to 120°.
- Remains fully concealed within the door and frame, with no visible arm or body on the door face.
Who It Helps
- Architects and specifiers needing a fire-rated, EN1154-certified door closer for commercial or institutional fire doors.
- Facility managers and contractors fitting heavy doors (80-120 kg) in offices, hotels, hospitals, or retail spaces.
- Fitters and hardware dealers sourcing a tested, high-cycle door closer for doors 850-1100 mm wide.
- Homeowners or designers wanting a hidden door closer for a minimalist door aesthetic.
