Overview of our models

What are the specificities of our espagnolettes bolts?

Unique piece of work

We offer handiworks that are unique in their design. Our products are made by skilled craftsmen. To obtain perfect results, we manufacture our products in an artisanal manner.

Each piece passes through our hands several times. Even within our workshops, we give all our know-how to create unique works. By carefully observing the elements you will notice not only the natural symbols but also those of animals.

Tailor-made according to the wooden windows and doors

When you order espagnolette bolts for your wooden windows, the results are tailor-made products.

You don’t have to make any adjustments once you receive the products. Our espagnolette and cremone bolts are authentic, manufactured according to the requirements of architects of French buildings (ABF). A standard valid for all our products.

Simply delivered as a complete package

It might seem surprising, but when we talk about complete provision, we don’t skimp on words. 

All production is therefore delivered with all its accessories, screws included. Real screws that fit perfectly to the historical products.

Authentic colour directly from the factory

When leaving the workshop, our products are made of raw iron with the natural colour of steel. Without any special request from you, we deliver the product to you in its authentic raw colour of steel. We can also apply a “black oxide” finish and impregnate it in wax which slightly blackens the product while protecting it from corrosion. The treatment is called blackening and it is realised in hot baths.

Frequently asked questions on espagnolettes

What's the difference between an espagnolette and a cremone bolt?

Espagnolette and cremone bolts are both locksmithing systems used to operate wooden windows and doors. Although the cremone bolt is a more recent mechanism, both systems coexist today, and the choice between cremone and espagnolette bolts often depends on personal preference and architectural style. The two mechanisms work in different ways. The espagnolette bolt consists of a single rod with hooks at the ends, operated by the handle. Espagnolette bolts are often used for double-sash windows (traditional French windows) and interior doors. They can also be adapted to single-leaf windows, and they can close interior wooden shutters in a single operation. Cremone bolts, on the other hand, are used to close wooden windows or interior doors, particularly in Haussmann-style apartments. The major distinction between espagnolette and cremone bolts also lies in their direction of movement. The rods of a cremone bolt move vertically, up and down, while the espagnolette rod rotates, allowing the hooks to be inserted into the window frame to close it.

How do I replace an espagnolette?

The espagnolette bolt is a closing device traditionally used on “mouton et gueule de loup” windows. When restoring or replacing joinery, the question of reusing espagnolettes naturally arises. The espagnolettes made by our locksmith ancestors were durable pieces of work, destined for years of use. It is possible to reuse espagnolette bolts for both replaced and renovated windows. Our workshop can repair or replace worn parts such as handle pivots, caps and mounting plates. And where necessary, the workshop can even reproduce elements identically to the existing model, as close as possible to the old design, while respecting the proportions and color of these elements. In addition, to facilitate installation of the original espagnolette, surface-mounting “on plates” can be proposed. This suggests a practical approach to integrating the espagnolette aesthetically when renovating or replacing windows.

Why do we say "à l'espagnolette" in French?

The term “espagnolette” has its origins in the fact that the espagnolette handle or turning hand of the window is designed and then manufactured with a small notch. This notch is used to lock or position the handle on the handle chuck to keep the sashes ajar. The espagnolette thus offers a practical solution for partial casement opening.

How does an espagnolette bolt work?

The espagnolette operates differently from the cremone bolt. Whereas the cremone bolt is a simpler mechanism, consisting of two often half-round rods that move vertically, ensuring 2-point closure, the espagnolette operates on a 3-point system. It is fitted with a single iron rod, whose diameter varies between ten and twenty-two millimeters, and whose ends terminate in hooks. By turning the handle, the rod rotates, and the hooks are inserted into the window frame and secured to the pins. The espagnolette is used on both doors and windows, with or without internal shutters. In addition, there is a type of espagnolette specially designed to close external shutters.

How to dismantle an espagnolette?

To dismantle a traditional espagnolette, first unscrew the nuts on the outside of the window and then remove the assembly. It’s not uncommon for the fixing plates to become damaged by the weather over time, which can weaken the espagnolette’s hold in place. However, a common challenge during disassembly lies in the laces screwed by the nuts to the outside, which can rust and make removal difficult. In such cases, it may be necessary to cut the nuts and screws with a grinder, which can unfortunately damage the espagnolette.
