Fire-Rated Door Viewer 14mm EI 30 Adjustable 35-60mm Matte Chrome

Product Overview

The Wizjer drzwiowy is a fire-rated door viewer with a 14 mm diameter, designed for installation in residential or commercial door leaves. Adjustable to fit door thicknesses from 35 mm to 60 mm, it is manufactured in a matte chrome finish suitable for modern architectural interiors. The product is certified to EI 30 fire-resistance standards, ensuring compliance for fire-rated entry doors.

Its EI 30 fire rating is the key differentiator, providing a certified 30-minute barrier against fire penetration at the viewing port?an area often overlooked in standard door viewers. This eliminates a common procurement risk for projects requiring full-door opening integrity certification. The product is especially recommended for multi-family residential buildings, hotels, and public sector facilities where fire-safety compliance is mandatory for all door hardware components.
