KOBLENZ KARAKTER K8080 Concealed Hinge 3D Adjustable Matte Chrome 80kg CE UL

Product Overview

The KOBLENZ KARAKTER K8080 concealed hinge is designed for high-quality fire-rated and flush wooden doors in both residential and commercial projects. Built from high-strength low-alloy (HSLA) steel and finished in Full HD matte chrome, this hinge assures enhanced durability and uniform appearance across all visible elements. It supports doors up to 80 kg on two hinges or 100 kg with three hinges, and is certified CE, UL, and by Applus laboratories for product consistency and performance in demanding conditions.

The signature feature of the K8080 is its triple-axis (3D) adjustment capability, allowing fine-tuning for horizontal (+3/-2 mm), vertical (+3/-3 mm), and depth (+1/-1 mm) alignment with a standard Allen key. This precise adjustability significantly reduces installation time and post-install correction costs, supporting fit-out contractors and OEM manufacturers working with premium doors where tolerance and finish are critical. Ideal for specification on fire-rated or high-value architectural panels where mechanical reliability and aesthetics are equally important.
