GEZE BOXER EN 2-4 2V Concealed Door Closer Latching Damping Valve EN 1154 130kg

Product Overview

The GEZE BOXER EN 2-4 2V concealed door closer with an additional latching action damping valve is designed for swing doors in both interior and exterior settings. It is suitable for wooden, aluminium, steel, and PVC doors with leaves up to 1100 mm wide and weighing up to 130 kg, and meets the EN 1154 standard for controlled closing. Installation is fully integrated into the door leaf (minimum thickness 40 mm), with the sliding rail mounted in the frame, supporting discreet architectural requirements.

A key differentiator of this variant is its additional valve for damping the final closing stroke, enabling fine-tuned, stepless adjustment of the latching phase directly from the top edge of the leaf. This feature minimizes the risk of noisy or damaging door slams, reducing maintenance calls in high-use environments. Particularly recommended for fire- and smoke-rated doors in commercial real estate or public sector projects where performance and adjustability are critical for compliance and lifecycle cost control.
