Yes. They are commonly fitted to bottom-hung hopper windows where controlled opening, support and safer airflow are important.

Do quadrant arm stays come as a pair?

What Are Polished Chrome Quadrant Arm Stays?

A quadrant arm stay is a type of window stay that controls how far a window can open by using a rigid arm and quadrant mechanism. On fanlight and hopper windows, the stay helps prevent overextension and supports the sash while allowing consistent airflow. The polished chrome finish brings a bright, modern look and is easy to wipe clean.

Best For Fanlight & Hopper Windows

These stays are most commonly used on inward-opening fanlight and bottom-hung hopper window styles. Because these windows often open from the top (inward), a dependable stay is essential for keeping the opening angle controlled—especially in bathrooms, upper floors, and commercial settings where ventilation and safety need to work together.

Key Benefits

Controlled opening: helps keep ventilation consistent and reduces the risk of the window swinging too far.
Improved safety: limits opening where a wider aperture could be risky (ideal for upper-storey rooms).
Durable finish: polished chrome resists everyday marking and is simple to maintain.
Neat appearance: complements chrome handles, hinges, and other window or door hardware.

Where Polished Chrome Works Best

Polished chrome is a popular choice for kitchens, bathrooms, and modern refurbishments thanks to its bright appearance and easy-care surface. It also pairs well with white frames, grey interiors, and contemporary hardware finishes. If you’re matching existing fittings, polished chrome quadrant stays can help keep your window hardware looking consistent throughout the property.

Installation Notes & Choosing the Right Stay

Quadrant arm stays are typically fitted in pairs, connecting the window sash to the frame to support the window and restrict the opening angle. When choosing the correct stay, consider the window size, weight, and how far you want the fanlight/hopper to open.
