ARGENTA Medium Concealed Hinge 111x29mm EN 1634-1 EI 30 Fire Door Matt Chrome

Product Overview

Argenta Invisible Medium hinge (111x29 mm) is engineered for flush-fitting wooden interior doors, including fire-rated EI 30 assemblies. Its concealed design enables doors to close as a continuous plane with the frame, meeting EN 1634-1:2008 fire-resistance requirements and EN 13501-2:2007 classification. Suitable for use with wooden or stainless steel frames, it is built for commercial or residential installations where safety and aesthetics are paramount.

A patented adjustment system permits three-directional regulation?height, offset, and depth?without removing the door leaf, setting this hinge apart from generic invisible hinges. This feature minimizes installation labor and error, making it particularly apt for projects requiring precise alignment, such as bulk procurement for fire-rated interior doors in hotels, office buildings, and high-demand multifamily housing.
