The UPVC Window Locks mechanism is the gearing part inside a window that's driven by a handle. The upvc window lock below shows one of many different types. The long metal plate is the rail and the part in the centre of the window lock is the gearbox. The lock is commonly used for locking the windows. The uPVC window has a wide range of hardware that could be incorporated into it and designed in such a way to be able to accommodate them. The UPVC Window Locks are made available by us as per the need.
