Griffwerk Elements of Perfection

Griffwerk, based in Blaustein, Germany, has built its reputation on combining engineering and minimalist design in door hardware, especially through innovations like Smart2Lock, which integrates the privacy lock into the handle itself for a cleaner look and one-handed use.


The design collection covers a wide range of door handles to suit every design — from clear, geometric shapes for modern rooms to gently curved handles for classic environments.


To meet the exacting design standards of world-class architects and interior designers, Griffwerk offers a variety of finish options, including stainless steel, graphite black, cashmere gray, and velvet gray.
