Replacing a broken or outdated window handle? Before buying a new one, it’s important to identify what type of uPVC window handle you have. With so many styles and measurements, choosing the wrong handle can lead to poor fitting — or worse, a security risk.
In this guide, we’ll help you quickly and confidently identify your existing handle, take the right measurements, and point you to the correct replacements available from our expert team at Home Secure Shop.
Types of uPVC Window Handles
There are three main types of uPVC window handles used across UK homes:
🛠 1. Espag Handles
-
The most common type, used on modern windows
-
Operates a multipoint lock by turning a spindle
-
Usually secured with two screws
-
Spindle protrudes from the back and connects into the lock mechanism
-
Often has key-locking functionality for added security
🛠 2. Cockspur Handles
-
Common on older uPVC and aluminium windows
-
Has a “spur” that catches on a wedge to keep the window closed
-
No internal lock mechanism — the pressure keeps the window shut
-
Easy to identify due to the curved spur design
🛠 3. Tilt & Turn Handles
-
Found on windows that open inward or tilt for ventilation
-
Features a longer spindle and often includes key-locking
-
Distinct due to their design and movement style
How to Measure a uPVC Window Handle
Once you’ve identified the handle type, you'll need to measure:
-
Spindle length (Espag and Tilt & Turn):
Measure from the base of the handle to the tip of the spindle.
Common sizes include 15mm, 30mm, and 40mm. -
Screw hole spacing (Espag & Cockspur):
Usually measured in mm between the two screw holes (centre to centre). Common sizes include 43mm or 64mm. -
Backplate width (Cockspur):
Ensures proper alignment with the existing frame.

Frequently Asked Questions (FAQ)
What’s the difference between Espag and Cockspur handles?
Espag handles operate a spindle-driven locking system, while Cockspur handles rely on a curved spur that presses against a frame wedge.
How do I measure spindle length?
Measure from the base of the handle to the tip of the spindle. The most common sizes are 15mm to 40mm.
Can I replace a Cockspur with an Espag handle?
No — they use different locking mechanisms. You’ll need to match the handle type to the window mechanism unless you plan to change the window internals.
