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

Product Overview

Assa-Abloy DC140 door closer with standard arm is suitable for a wide range of door types, including fire-rated and smoke-control doors, in commercial and institutional buildings. Certified to EN 1154 with adjustable closing force levels EN 2/3/4/5, it accommodates doors up to 1250 mm wide and 100 kg in weight. Thermodynamic valves eliminate the need for seasonal adjustment, offering reliable performance in various temperature conditions.

The differentiating feature of the DC140 is its adjustable closing force simply by repositioning the arm, eliminating on-site calibration steps and reducing installation complexity. This makes it a strong choice for facility managers and contractors overseeing large-scale upgrades, where consistent setup and minimal maintenance are critical, particularly in bulk procurement for office complexes or institutional projects.
