Choosing the Right Stay for Your Windows

Sizes, Styles & Security Features Explained

Casement window stays are designed to hold open outward-opening timber windows and provide secure closure when shut. The most commonly used sizes are:

8" (200mm): Ideal for small or narrow windows
10" (250mm): Best all-round size for most homes
12" (300mm): Perfect for larger or heavier timber windows

If you're renovating a period property, consider heritage styles like monkey tail stays or bulb end designs in beeswax or antique brass finishes. For more modern interiors, chrome and satin nickel finishes offer a clean, minimal look.

We also offer both locking window stays and traditional non-locking styles. For added security on older stays, a locking pin can be fitted as an accessory.
