Wizjer drzwiowy 27mm Door Viewer 180° Angle Chrome-Satin for 40-70mm Doors

Product Overview

The Wizjer drzwiowy with a 27 mm diameter is a door viewer designed for installation in entry doors with a thickness range from 40 to 70 mm. It serves as a passive security solution for residential or multi-unit buildings, allowing occupants to view visitors without opening the door. Its robust build and adjustable length make it compatible with various door leaf sizes in both new and retrofit settings.

The standout feature of this model is its wide 180-degree viewing angle, providing a significantly extended field of view compared to standard viewers. This enhances entryway security by reducing blind spots, which is advantageous for property managers and facility operators concerned about unauthorized access or building safety. Especially well-suited for bulk procurement in housing developments and multi-family residential projects where wide compatibility and improved visual coverage are required.
