ASSA ABLOY DC120 Door Closer Body EN 2/3/4 Brown Thermodynamic Valves EN 1154

Product Overview

Assa-Abloy DC120 is a door closer body (without arm) suitable for installation on a wide range of doors, including fire-rated and smoke-control models. With an EN 1154 certification, it supports adjustable closing force (EN 2/3/4) for doors up to 80 kg in weight and a maximum width of 1100 mm. Mounting options include hinge side on the door leaf or opposite side on the frame, supporting both left-handed and right-handed doors in commercial and residential environments.

The defining feature of this DC120 SKU is its integrated thermodynamic valves, which automatically compensate for temperature changes, eliminating the need for seasonal adjustment. This ensures long-term consistency in closing speed, reducing maintenance demands for facility managers and installers. As it is supplied without an arm, it is especially suitable for OEM assembly lines or projects requiring separate procurement of arms to match specific door layouts.
