Cadenza Window Handles
Cadenza window handles are specialist replacement handles designed for older aluminium windows and some early uPVC window systems that use a blade or spade to operate a multi-point locking gearbox. Unlike modern espag window handles, Cadenza handles do not use a square spindle. Instead, the locking mechanism is driven by a solid steel blade beneath the handle, making it essential to match both the blade style and blade length when replacing an existing handle.
Our range of Cadenza handles includes both flat blade and angled blade designs to suit the two original operating systems. Available with key locking, left and right handed options and multiple blade lengths, they provide a reliable replacement for worn or damaged original fittings whilst maintaining the appearance and operation of older window systems.
Before ordering, carefully compare your existing blade with the replacement. Although the fixing centres remain the standard 64mm and 84mm, the blade profile is the most important measurement. If you are unsure which model you require, browse our complete range of window handles or visit our guide covering the main types of window handles to help identify your existing fitting.
Choosing the Correct Cadenza Window Handle
Unlike many replacement window handles, Cadenza window handles are selected primarily by the blade underneath the handle rather than a square spindle.
- Blade profile – Flat (perpendicular) or Angled (leaning).
- Blade length – Commonly 18mm, 30mm, 35mm or 48mm depending on the model.
- Blade size – Standard 15mm × 3mm cross section.
- Fixing centres – 64mm (inner) and 84mm (outer).
- Handing – Left or Right handed.
The flat and angled blade versions are not interchangeable. Even though they share the same fixing centres, using the incorrect blade profile will prevent the locking mechanism from operating correctly.
If your existing handle uses a square spindle rather than a blade, you probably require an espag window handle instead.
Flat Blade or Angled Blade?
There are only two types of Cadenza handle available, making identification relatively straightforward once you inspect the blade beneath your existing handle.
W40 Flat Blade uses a straight blade that projects at 90 degrees from the backplate and is commonly found on many early aluminium and first generation uPVC windows.
W62 Angled Blade uses a leaning blade which sits at an angle beneath the backplate and is fitted to many older aluminium window systems using a different gearbox design.
If you're uncertain which version you need, our Window Handle Identification Guide explains how to compare the two blade styles before ordering.
