ASSA ABLOY DC140 Door Closer with Arm EN 2/3/4/5 Silver 1250mm 100kg EN 1154

Product Overview

The Assa-Abloy DC140 Door Closer with arm is designed for universal application on single-leaf doors, including fire-rated and smoke-control doors, in commercial, public, and residential environments. Its compliance with EN 1154 ensures suitability for safety- and code-critical installations, offering adjustable closing force across EN 2/3/4/5, supporting door wings up to 100 kg and 1250 mm wide. It operates with thermodynamic valves and requires no seasonal adjustment, offering high reliability in variable climate conditions.

The DC140's standout feature is its tool-free closing force adjustment via simple repositioning of the arm, allowing installers to quickly adapt the closer for doors of differing widths and weights without complex recalibration. This reduces installation time and post-setup corrections, lowering labor costs and minimizing error risk. It is particularly recommended for facility managers, hardware wholesalers, and bulk procurement in projects with mixed-use door specifications requiring quick configuration changes.
