ASSA ABLOY DC120 Door Closer with Arm EN 2/3/4 Silver 1100mm 80kg EN 1154

Product Overview

Assa-Abloy DC120 door closer with arm and cover is engineered for installation on a wide variety of door types including fire-rated and smoke-control doors. Certified to EN 1154, it delivers closing force levels EN 2, 3, and 4 (adjusted by arm position), accommodating doors up to 1100 mm wide and 80 kg weight. Thermodynamic valves eliminate the need for seasonal adjustments, providing consistent performance in commercial, institutional, and public sector buildings.

The DC120 stands out due to its closely spaced mounting holes in the cast body that allow direct installation without a mounting plate, reducing hardware costs and speeding up installation. This feature is particularly valuable for large-scale or retrofit projects where minimizing installation complexity and downtime is critical, making it ideal for bulk procurement in building renovation and fit-out contracts.
