What are casement window stays used for?

Casement window stays are used to hold timber or wooden casement windows in an open position and to prevent them from swinging in the wind. They also help control how far the window opens, and locking casement stays can add an extra layer of security.

Should I choose a locking or non-locking casement window stay?

Locking casement window stays are a good choice if you want additional security and to help meet insurance requirements. Non-locking stays are suitable where security is less of a concern. If your chosen stay does not have an integrated lock, you can usually add a separate locking pin as an accessory.

Can I match my casement stays with other window furniture?

Yes. Casement window stays can be paired with matching casement window fasteners and other window furniture for a consistent look. Many ranges from UK brands such as Carlisle Brass, Heritage Brass, Frelan Hardware, and From The Anvil offer coordinated styles and finishes across their window hardware collections.

Are casement window stays suitable for all types of windows?

Casement window stays are typically designed for timber or wooden casement windows. They may not be suitable for every type of uPVC or aluminium window system, so it is important to check the product details and your window construction before ordering.

Casement Window Stays

Q: What size casement window stay do I need?

Most homes use 8 inch (200mm), 10 inch (250mm), or 12 inch (300mm) casement window stays. The 10 inch (250mm) option is generally the most versatile for standard timber windows, while 8 inch or 12 inch stays may be better suited to smaller or larger window sashes.

Q: What finishes are available for casement window stays?

Casement window stays are available in a wide range of decorative finishes, including antique brass, black powder coat, polished chrome, beeswax, pewter, and satin nickel. This helps you match your stays with other window furniture and the overall style of your interior or period property.
