Designed for discreet integration and dependable performance, this concealed door closer with Cam-Motion technology and guide rail is ideal for single-leaf doors in size ranges 3 to 6. Fully hidden within the door leaf, the DC870 preserves the visual impact of modern entrance designs while delivering smooth, controlled door operation for all users.

Adjustable power settings simplify specification and installation, while durable, top-facing metal valves ensure precise and reliable fine-tuning. The unit performs consistently across a wide temperature range and is certified to EN 1154 standards (size 3–6).

Suitable for fire and smoke protection doors, the DC870 accommodates single-leaf doors up to 1400 mm wide and supports barrier-free access in accordance with DIN 18040 and CEN/TR 15894 guidelines. The result is a high-performance, unobtrusive door control solution that combines accessibility, safety, and design freedom.
