ASSA ABLOY DC175 Door Closer Sliding Rail EN 3/4 Cam Motion 1100mm Silver

Product Overview

The Assa Abloy DC175 overhead door closer with sliding rail is designed for single-leaf right or left-handed doors, supporting door widths up to 1100 mm and a weight of up to 80 kg. Certified according to EN 1154 and suitable for fire and smoke control doors, it features a compact body depth of only 33 mm, enabling installation in restricted spaces commonly found in office, residential, and public sector buildings.

A standout feature of the DC175 is the Cam Motion technology, which assists with door opening to meet barrier-free access requirements.

The Cam Motion system makes this model particularly well-suited for institutional projects in healthcare, education, and public buildings where inclusive access and ease of operation are specified requirements.
