Anselmi Istar 521 (AN 150 3D) Concealed Hinge Nickel Matte 927.56.026

Product Overview

The Anselmi Istar 521 (AN 150 3D) is a concealed hinge for wooden, rebated-free (flush) doors, including those requiring fire resistance. Designed for use in residential and light commercial interiors, this Italian hinge offers complete invisibility when the door is closed, aligning flush with both door leaf and frame. Its robust zamak construction and coverage for door thicknesses from 35 mm upwards ensure compatibility with a range of door types and institutional settings.

A defining advantage of this model is its 3D adjustability, enabling precise positioning in vertical, horizontal, and pressure directions without removing the door. This feature streamlines installation and long-term maintenance, minimizing labor for contractors and facility managers. The product is specifically suited for projects that demand a flawless architectural finish and fast alignment on-site, such as high-end residential developments or fire-rated interior doors in hotels or offices.
