The Rustic Roller Arm Stay is designed for bottom-hung, inward-opening windows, hanging vertically when the window is closed so that they do not project into the room. As the window opens, the stays pivot outward, supporting the casement as it falls inwards and preventing the sash from dropping. They allow the window to open to a fixed distance equal to the length of the stay, ensuring controlled ventilation. With a traditional design and durable construction, these stays are ideal for period properties, adding both functionality and rustic charm to heritage and country-style interiors.
