When designing the Griffwerk TRI 134 handle profile, we took a close look at the cavity that the hand forms when gripping. In the process, we realized that this cavity resembles neither a circle, an oval nor a rectangle, but rather has the shape of a gently rounded triangle.
Based on this insight, we developed a completely new handle profile with three sides in Blaustein. The result is Griffwerk TRI 134, a door handle that is literally "made for the hand". Its ergonomic design not only offers unique comfort, but also gives your door a timeless and elegant character. Experience the perfect combination of functionality and design with Griffwerk TRI 134.

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.
