GEZE BOXER 099728 Concealed Door Closer EN 2-4 For 1100mm 130kg Min 40mm Door

Product Overview

The GEZE BOXER concealed door closer EN 2-4 is designed for complete integration inside the door leaf, making it nearly invisible in closed position?only the sliding rail is visible when the door is open. Used primarily in commercial and institutional interiors where discreet hardware is required, this closer accommodates left or right rebated doors meeting EN 1154 certification for assured quality and safety compliance.

What distinguishes this model is its continuous, stepless adjustment of closing force (EN 2-4 or 3-6, depending on installation) and closing speed, all accessible from the door's top edge even after installation. This functionality minimizes commissioning time and allows for easy post-installation adjustments, reducing both labor and risk in projects with varying on-site requirements. It is particularly suited for premium commercial interiors, office or hotel projects, and bulk procurement where aesthetic concealment and post-mounting tuning are necessary.
