ASSA ABLOY DC140 Door Closer Without Arm Silver EN 2/3/4/5 to 100kg 1250mm EN 1154

Product Overview

The Assa-Abloy DC140 Door Closer (without arm) is engineered for commercial and institutional doors, supporting fire, smoke, and standard door types. Certified to EN 1154 and offering adjustable EN 2/3/4/5 closing force, it is suitable for doors up to 100 kg and 1250 mm wide, with reliable operation ensured by thermodynamic valves for temperature resistance.

A defining feature of the DC140 is its force adjustment by mounting position, allowing the same closer body to match different door requirements through installation technique?minimizing inventory complexity for large-scale procurement. This adaptable setup is particularly advantageous for facility managers and building contractors standardizing hardware across both fire-rated and general-purpose doors in new or retrofit projects.
