Cockspur Window Handles
Cockspur handles are often found on older type windows which do not have an internal mechanism ( a small square drive that can be seen if you remove the handle) to secure the window
Cockspurs are also found on windows which have a slim frame such as caravans or mobile homes. The handle locks by means of a spur (little triangle bit) pulling up against a plastic wedge that is found on the window frame.
As a general rule Aluminium window frames use a 9mm handle and UPVC frames tend to use a 21mm handle but this is not always the case and many other sizes are made.
The important measurement needed is the stack height which is the distance from the base of the handle to the underside of the spur, if you're not sure how to measure this click here to see a picture showing the stack height.
FAQ Cockspur Window Handles
What is a Cockspur?
The spur is the small part that sticks out of the side of the handle that pushes against the closeing wedge when the window is shut.
What is the stack height and how do I measure it he Spindle length.
First you need to remove the Handle from you window. This is done by removing the two fixing screws that hold the handle on. To do this open the window handle, remove the screws that you can see with a screw driver. Once the first screws are removed then you close the handle and flick off the screw cover that is covering the second lot of screws. Remove the second lot of screws and the window handle will come away in your hand. Once this is done you measure the stack height using a tape measure. ALWAYS measure the height with the handle flat on a surface.
Are Cockspur Window Handles Handed?
YES, all cockspurs are handed so you will need to check which hand you have at the minute. If the spur points to the left then you need a Right Handed handle. If it points to the right you need a left handed handle. (yes It is a bit confusing) there is a diagram on how to do this here
