ASSA ABLOY DC140 Door Closer with Arm EN 2/3/4/5 Black Adjustable Back-Check 100kg 1250mm

Product Overview

Assa-Abloy DC140 is a door closer with arm, designed for use on a wide range of door types including fire and smoke protection doors. Certified to EN 1154, it supports variable closing forces (EN 2/3/4/5), accommodates doors up to 1250 mm width and 100 kg weight, and is equipped with thermodynamic valves for stable operation in fluctuating temperatures. Mounting flexibility allows installation on both hinge and opposite hinge sides, on the door leaf or frame, without the need for seasonal adjustment.

The stand-out feature of this model is its adjustable back-check function, which offers wind-stopping action from 75° via a dedicated valve. This enhancement is especially relevant for project managers and installers seeking to protect doors and walls in high-traffic or exterior-exposed commercial and institutional environments. The DC140 is well suited for B2B procurement in property management, new build, and retrofitting scenarios where certified fire/smoke safety and installation versatility are required.
