A door handle is not just a design element: it must offer a comfortable grip, have dimensions proportionate to the door leaf, and use a fixing system compatible with the door. When comparing stainless steel models, the differences between straight, offset, tubular and rectangular can affect both aesthetics and everyday practicality.
In this Datek guide, we look at how to choose a handle for an entrance door, how to read the length and centre-to-centre distance, and what checks to make before purchasing, with real examples from the Brackle range available in our catalogue.
Door handle: when to choose one and on which entrances
Handles are particularly popular on entrance doors, contemporary-style doors and commercial entrances. Compared to a classic lever handle, they offer a grip that extends vertically or horizontally and become a visible part of the door's architecture.
Before choosing the shape, always check the type of door leaf, its thickness, the opening system and the mounting preparation. An external handle does not automatically replace the lock, cylinder or other necessary devices: these elements must be designed to work together.
You can start with the Datek door handle collection, which includes straight, offset and curved models in various sizes.
Straight or offset handle: what are the differences?
Straight handle: essential geometry
The straight handle features a linear bar, often parallel to the door face, attached to the leaf via special supports. It is a suitable choice for those looking for a neat aesthetic, especially on smooth entrance doors, metal doors and minimalist entrances.
Among the models in the catalogue, you will find the Brackle 301 straight rectangular handle, made of AISI 316 stainless steel with a satin finish. It is available in various length and centre-to-centre distance combinations.
Offset handle: a more spaced-out grip
The offset handle features an offset design or supports that change the distance of the grip area from the door surface. The result is more dynamic and can make the grip practical on leaves with special frames or proportions.
To compare this solution with the linear one, you can view the Brackle 301 rectangular offset. Before choosing, check the model's actual projection and the available space around the door leaf.
Tubular or rectangular handles: how does the style change?
The bar's cross-section affects the visual appearance and the feel of the grip. Tubular handles, with a cylindrical profile, create soft, continuous lines. Rectangular or square models, on the other hand, emphasise the geometries of modern doors, glass and metal frames.
For an understated style, you can compare the Brackle 302 straight tubular handle with the 302 tubular offset. Both are described in the catalogue as AISI 316 stainless steel with a satin finish, but they feature different geometries.
If you prefer a bar with a bolder geometric profile, the Brackle straight square handle is another alternative to consider.
Handle measurements: difference between length and centre-to-centre distance
One of the most common mistakes is confusing overall length and centre-to-centre distance. They are not synonyms:
- Overall length: the handle's total measurement, which determines its visual presence on the door.
- Centre-to-centre distance: the distance between the centres of the two fixing points, which is essential when holes are already present in the door leaf.
- Projection: the distance between the grip area and the door face, which should be assessed especially on profiles, frames and narrow passages.
A concrete example: the Brackle 301 straight rectangular product page features a variant that is 1200 mm long with a 900 mm centre-to-centre distance. This means that the fixing points are spaced 900 mm apart, not 1200 mm.
The same model also offers other measurements: check the selected variant before purchasing. If you need to replace an already installed handle, measure the holes from centre to centre, without relying solely on the bar's external length.
Brackle 303 and 304 curved handles: which one to choose?
Not all handles need to have a perfectly straight profile. The range also includes curved solutions, appreciated for their softer grip shapes.
The Brackle 303 handle has a tubular profile with a stated diameter of 25 mm and a 300 mm centre-to-centre distance. The Brackle 304 maintains a curved design but has a 400 mm centre-to-centre distance.
The choice between the two depends primarily on the required fixing arrangement, the size of the door leaf and the desired proportions. They are not interchangeable if the existing drilling is different.
AISI 316 stainless steel: characteristics and maintenance
Several Brackle handles available on Datek are made of AISI 316 stainless steel, an alloy appreciated for its corrosion resistance compared to many commonly used stainless steels. This is an interesting feature when choosing an accessory for an exposed entrance, but it does not mean a complete absence of maintenance.
For particularly aggressive environments, such as those with salt spray, the surface finish, installation methods, periodic cleaning and manufacturer's instructions must be considered. Avoid harsh detergents or products that can contaminate the surface with ferrous residues.
The satin finish is also an aesthetic choice: it creates a softer reflection than a glossy surface and pairs well with metal, wood doors and contemporary door fittings.
How to check the fixing before purchasing
Even a model with the correct measurements can turn out to be unsuitable if the mounting system is not compatible with the door. Before ordering, check the following points:
- Material and thickness of the door leaf: wood, metal and glass may require different preparations and components.
- Type of fixing: through-fixing, single, or intended for other configurations; check what is specified in the model's product sheet.
- Hole distance: check the exact centre-to-centre distance, especially in the case of a replacement.
- Operating space: consider the opening, clearance, any frames and the presence of other accessories.
- Contents: compare the package contents and included accessories, avoiding assuming that the kit is universal.
If the handle is intended for glass doors or entrances with specific security and accessibility requirements, the fixing and the compliance of the entire installation should be assessed by a qualified technician.
Door handle or sliding door handle?
The term handle is also used for systems other than entrance doors. One example is the Brackle HS 508 handle pair, intended for sliding doors: it should not be chosen as if it were just any vertical entrance door handle.
First, identify the type of opening of your door fitting; only then compare the design, measurements and finish. If you are looking for a normal lever for interior doors, consult the Datek guide on how to choose door handles.
Frequently asked questions about door handles
What is the difference between a straight and an offset handle?
The straight handle focuses on a linear geometry; the offset handle uses an offset profile or supports. To choose, assess the grip distance, the useful space and the door's preparation.
Does a 900 mm centre-to-centre distance mean the handle is 900 mm long?
No. The centre-to-centre distance measures the distance between the centres of the fixing holes. The handle can be longer: for example, a 1200 mm model can have a 900 mm centre-to-centre distance.
Can an AISI 316 stainless steel handle be mounted outdoors?
It is a material often assessed for exposed applications, but its actual suitability also depends on the fixing, finish, environment and manufacturer's instructions. Stainless steel must still be cleaned and maintained correctly.
Can I install a new handle in the existing holes?
Only if the centre-to-centre distance and fixing system are compatible. Also check the diameter and position of the holes, as well as the thickness of the door leaf.
Which handle to buy on Datek Ferramenta?
If you are looking for a geometric design, compare the Brackle 301 straight with the 301 offset. For a cylindrical bar, you can consider the 302 tubular, while the 303 and 304 offer curved profiles with different centre-to-centre distances.
