ASSA ABLOY DC120 Door Closer EN 2/3/4 Thermodynamic Valves Black No Arm 1100mm

Product Overview

The Assa-Abloy DC120 is a compact cast-body door closer, supplied without an arm, certified to EN 1154 for controlled closing of fire and smoke protection doors. Designed for use on interior doors in commercial, institutional, and multi-residential buildings, it offers variable closing force settings (EN 2/3/4) for door widths up to 1100 mm and weights up to 80 kg. Mounting is possible on both hinge and non-hinge sides, with no mounting plate required due to closely positioned fixing holes.

The inclusion of self-adjusting thermodynamic valves is the DC120's key distinguishing feature, eliminating the need for seasonal adjustments and minimizing temperature-related performance variation. This saves maintenance time and ensures regulatory compliance across varying climate conditions, particularly valuable for facilities managers and bulk door hardware upgrades in mixed-usage environments.
