Friction stays are a type of window hardware that helps to keep windows open in a fixed position. They are typically used on top-hung windows, which are windows that are hinged at the top and open by swinging outward from the bottom. Friction stays work by applying a controlled amount of friction to the window sash, which prevents it from moving too quickly or too easily.
Mechanism of Operation
Friction stays consist of two main components: a friction shoe and a tension spring. The friction shoe is a flat, rectangular piece of metal that is attached to the window sash. The tension spring is a coil of metal that is attached to the window frame. When the window is opened, the friction shoe slides over the tension spring, which creates friction and slows down the movement of the window.
Types of Friction Stays
There are two main types of friction stays:
Single-arm friction stays: These stays have a single arm that extends from the window frame to the friction shoe. They are typically used on small windows.
Double-arm friction stays: These stays have two arms that extend from the window frame to the friction shoe. They are typically used on larger windows.
Advantages of Friction Stays
Friction stays offer a number of advantages over other types of window hardware:
Controllable opening: Friction stays allow you to control the amount of friction that is applied to the window sash, which means that you can adjust the speed at which the window opens and closes.
Smooth operation: Friction stays operate smoothly and quietly, making them ideal for use in homes and offices.
Durability: Friction stays are made of durable materials, such as aluminum and stainless steel, which means that they will last for many years.
Installation and Maintenance
Friction stays are relatively easy to install and maintain. They can be installed by a do-it-yourselfer with basic tools. However, it is important to follow the manufacturer’s instructions carefully to ensure that the stays are installed properly.
To maintain friction stays, simply clean them with a damp cloth and apply a light coat of lubricant to the friction shoe. This will help to keep the stays operating smoothly for many years to come.
