Hettich HCS 385: EN 2-4, With Hold Open Slide Rail - Concealed Door Closer
Overview
The Hettich HCS 385 is a concealed (invisible) door closer designed for heavy, wide doors. It uses a Rack and Pinion (Symmetric) mechanism and includes a hold-open slide rail, allowing the door to stay open at a set position instead of closing automatically every time. Because the mechanism is fully concealed within the door and frame, it preserves a clean architectural look while still delivering controlled, silent closing.

What It Does
The HCS 385 controls the closing motion of a door after it has been opened, using a hidden rack-and-pinion mechanism instead of a visible surface-mounted arm. The hold-open slide rail feature lets the door remain open at approximately 120° when needed (for example, during moving furniture or deliveries), rather than closing automatically. Closing speed and latching speed are both independently adjustable, so installers can tune the door's final approach and softer near-close behavior.
Who It Helps
- Architects and interior designers who need a door closer that stays hidden and does not disrupt door or frame aesthetics.
- Facility owners and contractors installing or replacing closers on heavy commercial or high-traffic doors.
- Hardware buyers sourcing a closer rated for wide, heavy doors (850-1100 mm width, 80-100 kg weight) where standard-duty closers are undersized.
