To measure the spindle on a window handle, you need to find the length from the base of the handle to the tip of the spindle.
Understanding how to measure the spindle is crucial when replacing a window handle, especially for common types like Espag handles. According to the reference, Espag window handles are largely universal, making the spindle length the primary measurement required.
Why Measure the Spindle Length?
The spindle is the metal bar (usually square) that connects the handle mechanism to the locking mechanism within the window frame. Its length determines how far it reaches into the mechanism, ensuring correct operation. A spindle that is too short won't engage the lock, and one that is too long might prevent the handle from sitting flush against the window frame.
Simple Steps to Measure the Spindle
Measuring the spindle is straightforward. Here’s how:
- Locate the Spindle: The spindle is the metal rod extending from the back of the window handle.
- Identify the Base: The base of the handle is where the spindle meets the main body of the handle itself.
- Measure from Base to Tip: Use a measuring tape or ruler to measure the length of the spindle from the base of the handle to the very tip of the spindle.
Reference Insight: As highlighted in the reference, "To measure the the spindle you measure from the base of the handle to the tip of the spindle." This is the standard method.
Visualizing the Measurement
Imagine the handle lying flat. The spindle sticks out. You place your measuring tape at the point where the spindle comes out of the handle's mounting plate or body and measure straight along the spindle to its end.
Here's a quick breakdown:
| Measurement Point | Start | End |
|---|---|---|
| Spindle Length | Base of the handle (where spindle exits) | Tip of spindle |
Common Spindle Sizes
Spindles come in various lengths, typically in increments of 5mm. Common sizes include:
- 10mm
- 15mm
- 20mm
- 30mm
- 40mm
- 43mm (a very common size for replacement)
- 50mm
- Up to 100mm or more for specific applications
When replacing a handle, it's best to get the exact spindle length or one slightly longer that can be trimmed to size if necessary.
Additional Measurements (Less Common for Espag Spindle Itself)
While the reference emphasizes the spindle length for Espag handles, other measurements might be relevant for the handle itself or different handle types, but not for the spindle measurement specifically. These might include:
- Handle screw hole centers
- Backplate dimensions
- Spindle width (usually standard 7mm square for uPVC)
However, for measuring just the spindle, the length from the base of the handle to the tip is the key.
Knowing this crucial measurement ensures you select the correct replacement handle, allowing your window to lock and unlock smoothly.
