Hand forged Iron Casement Stays


Windows are often referred to as ‘the eyes of a building’ and contribute significantly to the look and character of a property.

What is a Casement Window?

The casement window is hinged at the side and opens like a door, either out or in. They can be single or in pairs in a common frame.

A Brief History

The successor to the stone mullion, the traditional timber casement became the most common type of window by the end of the eighteenth century. Early designs had the opening part, the ‘casement’, made of iron with lead latticing to the glass. By the dawn of the Victorian period frames and casements were made entirely of timber. As glass technology improved the size of panes could be increased so the numbers of glass panes were reduced.

A History of Casement Window Hardware

Early casement windows would have had a casement latch and casement stay in black iron, often forged by the local blacksmith. In Victorian times window hardware could also have been cast in brass and in the later 1800’s and early 1900’s plated in nickel. Our ranges are copies of antique originals and our iron window fittings are hand forged. If you are looking for the right window fittings to suit your period property we can help. Our latest offering is Art Deco window furniture, cast from original moulds.

Glossary of Terminology

Please find an explanation of terminology used below:

Casement Fastener – A window fastener for casement windows, they generally have a handle which turns to release or close a snib which secures in a keep. The keep sits on the window frame. There are 2 types of keep:

Hook  – If your window and frame are flush when closed, you need the surface mounted hook plate, this sits on the front face of the frame.

Mortise  – If your window is recessed in the frame when closed, the fastener goes into the edge of the window and just needs the flat mortise plate to hide the hole. The majority of windows need these.

Some of our traditional casement fasteners have been adapted for modern situations and can be purchased as locking items. These come with a small allen key.

Handed Fastener – These are Casement Fasteners which work only one way, so they have to be ordered as a right hand or left handed fastener.

Reversible Fastener – A casement fastener which can be spun around  so will work on either the left or right hand side of a window.

Vented Fastener or Night Vent Fastener – Casement fasteners which have a closed position and a vented position. The vented position allows airflow whilst the window remains secured. Locking night vent fasteners allow you to lock the window in a vented or closed position.

Casement Stay – Arm which allows the window to stay open. They come in 3 lengths – the shorter the arm the smaller the opening. There are holes in the arm which sit down on pins to secure. You select which pin to secure on according to how wide you want the window open. Some come in lockable form.

Sliding Stay – A casement stay with an arm which slides in and out to open and close the window. It can be fixed in any position along the arm using a knob to lock it in place. These are not listed on our site but we can get these from our wider catalogue.

Espagnolette Systems

Espagnolette window lock – these are a modern method of locking a window in place. An espagnolette rod moves up and down to move the casement from open to closed positions.

Espagnolette Fastener – You need a special type of fastener to work with an espagnolette locking system. The fastener has a 7mm spindle in the back which fits into the espagnolette rod. We offer traditional looking espagnolette fasteners to use with these systems. These window fasteners can also be used with standard window locks which take a 7mm spindle.

Window Hinges – Used only on Casement windows. These are like the butt hinges used for doors and come in a variety of qualities and sizes.
