Before you upgrade your uPVC window handles with a brand new replacement you should know what size window handle you need. Before you purchase your new shiny chrome or brass window handle check the size of your current one. The main measurement you are looking for is the spindle length. The spindle is the piece of metal that sticks out of the back of the window handle and connects directly into the uPVC window. see fig.1
Spindle lengths can come in various sizes. Depending on your uPVC window profile you may need one of the following – 10mm, 15mm, 20mm, 30mm or 40mm. The biggest and most common window handle size is 40mm. This means that if you purchase a window handle with a bigger sized spindle you can easily cut it down to fit. For example, if you require a 20mm spindle yet you have a 40mm option then simply mark down where the 20mm mark is and use a saw to cut it off.
