Window lock repair by model
Window locks can break accidentally or due to the wear and tear caused by regular use. It is essential to determine the correct lock type for an effective window lock replacement.
People are sometimes tempted to replace the entire window, which makes repairs costs higher. If you notice any problem with your window’s locks or handles, it is advisable to replace them as soon as possible to avoid future inconveniences and security issues.
Below are some of the common uPVC windows handles
Espagnolette handles & inline + offset locking mechanisms
The handle is attached to a centre rod that operates mushroom-like locking cams. The lock’s spindle protrudes from the handle into the rod to activate the locking cams also known as locking mushrooms, this will then lock into window frame keeps.
In case of a broken handle, the opening mechanism won’t work, meaning you have to replace the lock or handle. Always ensure that you have measured the length of the spindles to ensure that you purchase a replacement with the right length. At Misty Glaze we can quickly identify the model over the phone to ensure you get the best service and an excellent price.
Cockspur handles
