TRI 134
Made for the hand
When designing the 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 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 TRI 134.

Graphite black
Black is finding its way into architecture, whether on large window fronts, as entrance doors or in interior details. Griffwerk offers the right selection of black fittings. A special feature is the black shade developed by GRIFFWERK, inspired by the black of graphite. The material look is reminiscent of black graphite powder, the feel is surprisingly soft. Graphite black impresses with its unusual, velvety matt finish and soft surface. Graphite black accents can be repeated in the room. They have a very noble effect and do not stand for elegant refinement and luxury for nothing. Griffwerk offers graphite black design in various product categories, allowing a holistic design of any interior. Graphite black is close to the RAL colour RAL 9011 (graphite black). Whether door handle, window handle, handle shell pair or even just handle bar, what is important is a uniform interplay of different colour elements that emerges from a conscious colour concept.
Anatomy and movement patterns guide design
In the search for the perfect haptic experience, GRIFFWERK tested a wide variety of profiles in several studies. Finally, several criteria could be defined that are relevant for a "perfect" gripping experience:
The "perfect" profile corresponds to the hollow space,of the closing hand. This is three-sided for anatomical reasons and not round or rectangular
During operation, the angle of the closed hand is changed, as well as the position of the user in space. The closed hand is therefore "moved" on the door handle. It does not remain static. The edges must therefore be softly rounded to allow for movement play.
Most pressure is exerted on the upper contact surface. This is also the largest contact surface between the door handle and the hand. It therefore plays the most important role for the grip feeling. It is particularly pleasant if it is kept very wide, as is the case with TRI.
The upper contact surface should also be inclined towards the door. An angle that slopes gently towards the door corresponds to the natural posture of the wrist when operating a door handle. Thanks to the inclined angle, the wrist is not hyperextended when pressing the handle (as would be the case with a horizontal surface).
Door handle TRI 134 was developed based on these criteria.
A new classic
Door handle TRI 134 is one of the simple, minimalist design forms that fit any door and any architectural style. In addition to a shapely, restrained design, it offers exceptional gripping comfort.
Haptic in perfection
We have developed a profile cross-section with a "perfect feel". Anatomical requirements and movement patterns were taken into account. The gripping area now has three sides and thus corresponds exactly to the actual cavity of the gripping hand. This is not round but has a three-sided shape due to the joints of the hand.
The Greek pronoun "TRI" ("three" or "threefold") therefore became the eponym of the first handle introduced with the new profile.
Its shape literally nestles against the hand.
DOOR HANDLE SETS
Door handle sets are door fittings that consist of door handles and the corresponding plates or rosettes and are used to open and close doors. Inside the door is a square lever handle pin, which is connected to a lever handle on both sides - via the so-called spindle part.
SQUARE ROSETTES
Square door rosettes are the rectangular or square plates that are fitted around the door handle and keyhole to cover the hole in the door leaf and provide a decorative as well as functional cover. In the square version, they offer a modern and angular design.
CLOSING TYPE WC
The "WC" locking type refers to special door locks for bathroom or WC doors that work without a key. These locks are usually locked from the inside by a knob or push button and often have an emergency release from the outside that can be operated with a coin or flat object. They offer privacy without the need for a key.
Door handles: FAQ
Yes, usually a screwdriver or cordless screwdriver is sufficient to remove the protective fittings and pull out the door handle.
A continuing trend: Black Door handles. Griffwerk offers a comprehensive range of these. The special feature: The black door handle is available from Griffwerk in the specially developed black shade Graphite black: particularly matt, high-quality, soft feel.
Many room doors in Germany use a square spindle with a square diameter of 8 millimeters. For BB and PZ locks, a center-to-center distance of 72 millimeters is common. However, deviations are possible—for example, with WC sets, fire- and smoke-rated doors, older doors, or fittings designed for other markets. Therefore, before ordering, measure the square shank size, the door thickness, the mounting distance, and the existing drilling pattern.
When selecting a door handle, you should distinguish between the base material and the visible finish. The key factors to consider are the intended use, frequency of use, desired feel, and the door’s design. For frequently used doors, a sturdy Lever handle set designed to withstand the intended wear and tear is recommended. Information on the tested usage category—for example, according to DIN EN 1906—can serve as a guide.
Door handles, stainless steel, are durable and available in a variety of finishes. Depending on the model, additional materials and finishes—such as graphite black, Cashmere grey, Brass effect, or Gold matt—are also available. Match the door handle to the door leaf, frame, and other hardware elements such as Window handles or light switches.
The weight of the door, however, is not a decisive factor in choosing the material for the door handle. It is primarily supported by the door leaf, hinges, door frame, and the overall door construction. Therefore, choose a door handle set that is technically compatible with the door and its intended use.
Escutcheons consist of door handle and cover or border of the door lock. Escutcheon fittings: Door handle and keyhole are connected with a metal plate ("door shield"). Interchangeable sets consist of two different door handles: on one side a classic door groff, on the other side a knob.
Half sets are characterized by the fact that one side has a completely different door handle installed than the other - mainly to connect two rooms with different interior style.
Clean door handles regularly with a soft, slightly damp cloth. None of the cleaning agents should be abrasive, chlorine-based, or harsh. For special finishes, follow the care instructions provided with the product. If you plan to use a disinfectant, it must be suitable for the finish in question.
Rosette door handles, escutcheon door handles, lever handles, half handles, Ulmer door handle - and all of this made from a wide variety of materials. In addition, there are long plates, short plates, fire protection fittings, security fittings and many more.
