Replacement Upvc Window Handles
Most replacement upvc window handles include everything you require, however if the previous handle had screws or pins that were holding it, they are required to be removed. Then, you need to remove the snap-in cover on the handle's base.
You'll need to identify what type of window lock and handle you're replacing. This is important!
Espag
Espag handles are a system of multipoint locks that are designed to fit on casement windows like uPVC or wooden double glazing. The handle is fitted with a 7mm square shaft that is fitted into a gearbox on the uPVC window. When the handle is turned, it will activate a series of locks around the perimeter of the window. Espag handles are also referred to as shootbolt handles. They provide more security than the typical single point lock that is used on older window frames.
