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

Product Overview

Assa-Abloy DC120 door closer is used for commercial and residential doors, including fire-rated and smoke-control classifications, and is certified to EN 1154. It supports doors with a leaf weight up to 80 kg and a maximum width of 1100 mm. Installation can be done on either the hinge side or the opposite frame side, and the unit operates reliably thanks to integrated thermodynamic valves which eliminate the need for seasonal adjustments.

What distinguishes the DC120 model is its regulated closing force across EN 2/3/4, achieved simply by repositioning the arm. This allows quick adaptation to varying door sizes and weights without extra parts or accessories, minimizing risk for procurement and installation. Facility managers, fire safety contractors, and bulk door hardware buyers will find it particularly suited for projects requiring compliance and versatility for both left and right-handed doors.
