The more we go into detail, the more questions there are... Here are the most frequently asked questions. if you can't find what you're looking for send us an email.

The material

What are our objects made of?

Our objects are made of brass.
Brass is an alloy composed mainly of copper and zinc .
This alloy can be recycled indefinitely without losing any of its properties.

Why Brass?

For its machining qualities first. Milling, bar turning, cutting are the main
techniques we use. These processes, unlike foundry, are energy efficient. It is also the metal best suited to receive veneers and patinas.

For its history too. The first brass objects date from the third millennium BC. It is the golden appearance of brass that has encouraged its growth in the field of ornamentation.

We are captivated by the play of shadow and light offered by this material.

Why do some finishes acquire a patina?

The NATURAL BRASS and MIRROR POLISHED finishes will take on a patina over time and use.

The copper present in the alloy oxidizes on contact with air. This patina is called "verdigris".

The straw yellow color of brass (comma removed) will turn golden yellow then slowly brown to approach a bronze hue.

The POLISHED MIRROR finish will patinate more slowly.

Brass is a living material.

However, it is possible to keep the appearance
original brass with regular maintenance and suitable products (find here ).

Design and manufacture

Who draws the objects?

Agnes and Manuel.

where are they made?

Our objects are made in France in family-sized companies equipped with extremely sophisticated machines.

Each company specializes in a machining station, mainly milling, bar turning and laser cutting.

The processing and finishing are carried out by other more artisanal companies where artistic qualities and know-how are paramount.
For the most part, these companies know each other and work closely together to optimize journeys.

We assemble and pack the objects in Bordeaux .

Installation & technical


Download assembly instructions here .

The handle is installed, however it has play, what should I do?

Case n°1: The conical screw (which is used to fix the handle on the square) has unscrewed.
It is located under the handle. By unscrewing, it no longer tightens the square.
It is therefore necessary to refit all the objects, without forgetting the nylon washer, then to screw the needle screw correctly into the handle. To screw it back on, use a 2.5 mm Allen key.

If you can no longer find the needle screw and the Allen key: order here .

Case n°2: The square is badly positioned.
During installation the square was turned upside down.

The countersunk recess of the square (the deepest) must be positioned on the needle screw side (facing down).

Case n°3: The thickness of the square is not suitable.
In some cases, the installer has placed the 7x7 mm square delivered with the handles in a lock whose follower measures 8x8 mm.
The handle wiggles. You must add an adapter (7->8 mm) to your square (to be ordered here ).

It also happens that the square measures 6x6 mm (this is often the case with old doors whose locks are applied). 6->7 mm adapters will then have to be inserted into each handle.

Case n°4: The square is too long.
The square that we supply with our handles is suitable for a standard door whose thickness is 40 mm.
Even if there is a little tolerance, the length of the square must be adapted to the thickness of your door (to be ordered here ).

Case n°5: The lock is loose
A lock, even of good quality, often has a little play (from top to bottom). But it happens that some locks are of poor quality or too old. In this case the play is too pronounced, the lock must be changed.

Can I use Bonnemazou Cambus handles on old doors equipped with surface locks?

Yes of course, you will have to contact us here because it requires a little adaptation.
The spring of these locks is often very tired, in this case the Olive Light handle will be suitable.
For the other shapes, we will need to know the opening direction on the case side (right hand or left hand).
Old and wall-mounted locks generally require a square of 6 mm in section, adapters are necessary.

Our parts are produced by machining, a technique that is much more energy efficient than foundry.
