Casement Window Stays

Heritage Brass Casement Window Stays

A traditional casement window stay is fitted between the opening sash and its frame. The stay bar engages with one of several locating pins, allowing the window to be held at different opening positions.

The correct stay depends on the window dimensions, construction, opening direction and available fixing area. Length alone does not guarantee compatibility, so review the complete product drawing before purchase.

Before ordering, check:

• The overall length of the stay
• The dimensions of its fixing plate
• The position and spacing of the locating pins
• The available space on the sash and frame
• The required opening distance
• Clearance around handles, glazing and window reveals
• Whether an additional locking accessory is required

Ball-End Casement Stays

Ball-end casement stays feature a rounded decorative finial at the end of the stay bar. Their traditional design can suit period-style timber windows and can be coordinated with matching ball-end fasteners.

Check that the handle end has enough clearance to be lifted from the locating pins. The bar should move freely through its complete operating range without striking the frame, wall or surrounding fittings.

Spoon-End Window Stays

Spoon-end window stays have a flattened, curved finial that creates a distinct traditional profile. They can be paired with coordinating spoon-end casement fasteners for a consistent set of window furniture.

Although spoon-end and ball-end stays work in a similar way, their plate dimensions, lengths and fixing positions may differ. Measure the window and existing hardware carefully when choosing a replacement.

Pear-Drop Casement Stays

Pear-drop casement stays feature a broader shaped finial and provide another traditional option for timber windows. Selected Heritage Brass designs are available in bronze finishes.

Consider the proportions of the stay in relation to the window. A decorative finial may require more operating clearance than a simple straight-ended design.

Sliding Casement Stays

A sliding casement stay uses a guided mechanism rather than a traditional perforated bar and separate locating pins. The mechanism allows a compatible sash to move while helping hold it at a selected position.

Sliding stays require sufficient space for the complete guide and moving components. Check the opening direction, mounting surfaces and operating path before installation.

Do not substitute a sliding stay for another design without confirming that it is compatible with the window’s size, construction and intended movement.

Quadrant Window Stays

A quadrant stay uses a curved or guided arrangement to control the movement of a compatible casement window. Its compact operation can suit window layouts where a conventional straight stay is unsuitable.

Check the orientation, fitting position and opening arc carefully. The components must remain aligned throughout the window’s movement and must not obstruct glazing, seals or surrounding joinery.

Casement Stay Locking Pins

Selected traditional window stays may be compatible with a locking pin that helps prevent the stay from being lifted from its locating point without first releasing the locking mechanism.

Confirm that the locking pin is designed for your selected Heritage Brass stay and check whether keys are supplied. A locking accessory should not be assumed to meet a particular security or insurance standard unless that performance is stated.

Choosing a Window Stay Length

The appropriate stay length depends on the size and proportions of the opening sash, the available mounting space and the required opening range. A stay that is too long may strike the frame or extend beyond the suitable fixing area, while one that is too short may unnecessarily limit the opening.

If replacing an existing stay, measure the complete bar and fixing plate rather than relying on a nominal size. Also record the location of the stay pins and their relationship to the sash.

Where no previous fitting exists, position a temporary measuring guide on the closed window and test the proposed movement before drilling.

Unlacquered Brass Window Stays

Selected ball-end and sliding window stays are available in unlacquered brass. With no clear protective coating, the surface responds to handling and its surroundings by developing a natural patina.

Frequently touched areas may brighten or darken differently from the rest of the fitting. Follow the product-specific care information and avoid polishing if you want to retain the naturally aged appearance.

Replacing Existing Casement Stays

Record the existing stay’s position and measure its overall length, plate dimensions, fixing centres and pin locations before removal. Check whether the replacement will cover old holes or marks.

Existing screw holes must remain strong enough to hold the new fitting. Damaged or weakened timber may require repair before installation.

Installing Window Stays

Plan the stay and pin positions with the sash closed, then test the intended movement before drilling. The stay should hold the window securely without forcing it against the frame or placing unnecessary pressure on the hardware.

Use screws appropriate for the timber thickness and take care around glazing and concealed components. Open and close the window fully after installation to check that every part moves freely.

Window Stays, Restrictors and Security

A standard casement stay is primarily a positioning fitting. It should not automatically be treated as a safety restrictor or security lock.

Where a formal opening restriction, child-safety provision or security standard is required, use products specifically designed and tested for that purpose.
