Step 1 – Open Your VELUX Window

Gently open your roof window so you can access the top edge of the sash (the moving part of the window).

The identification plate is not visible when the window is closed, so you will need to open it slightly to locate it.

Step 2 – Locate the Identification Plate

Once the window is open, look along the top edge of the sash. You’ll see a small metal plate or sticker fixed into the frame.

This plate contains important product details, including:

  • Model code
  • Size code
  • Additional manufacturing information

It’s usually silver, grey, or black with printed text.

Step 3 – Note Down the Window Code

On the plate, you’ll see a combination of letters and numbers.

For example:

  • GGL MK04
  • GGU CK02
  • GPL FK06

The size code (such as MK04, CK02 or FK06) is the most important part when selecting your blind. Make sure you copy it exactly as shown, including any letters.

Once you have this code, you can confidently choose the correct blind size in our calculator.

If you’re unsure or the label is worn or difficult to read, simply take a clear photo of the plate and contact us. We’ll be happy to help you confirm the correct window code before you place your order.

VELUX Key for Opening Restrictor (ZOZ 011)

The VELUX ZOZ 011 key is a dedicated release tool for use with the VELUX Opening Restrictor (ZOZ 010K). If your VELUX centre-pivot roof window has a restrictor fitted, this key allows you to override the limited opening position when full access is required.

It is an essential accessory for homeowners who have installed the VELUX safety restrictor and need occasional full opening functionality.

Release for Cleaning and Full Opening

When the opening restrictor (ZOZ 010K) is installed, the window can still open to a limited position for safe ventilation. To open the window beyond this point — for example, for cleaning or maintenance — the ZOZ 011 key is required.

This provides:

  • Controlled safety in everyday use

  • Secure limited opening

  • Temporary full release when needed

  • Practical access for cleaning

Designed Specifically for VELUX Opening Restrictor

The ZOZ 011 key is compatible with:

  • VELUX Opening Restrictor ZOZ 010K

It is designed exclusively for this system and ensures correct, safe release of the restrictor mechanism.
