ASSA ABLOY DC175 Door Closer Sliding Rail EN 3/4 Black Cam Motion 1100mm 80kg

Product Overview

The Assa Abloy DC175 door closer with sliding rail is designed for single-leaf right or left doors, commonly used in commercial and institutional facilities. Certified to EN1154 (classification 3 8 4/3 1 1 3), it supports doors up to 1100 mm wide and 80 kg. Its extremely compact body depth of just 33 mm makes it suitable for installation in limited overhead spaces.

What sets the DC175 apart is its Cam Motion opening assistance, which meets barrier-free building requirements and reduces manual force needed to operate heavy doors. This feature is particularly valuable for accessibility projects and compliance-driven installations in healthcare, education, or public sector buildings, enabling easier procurement of hardware for certified smoke- and fire-rated assemblies.
