The Espag window handle range is designed for multi-point locking windows with key locks that meet home insurance requirements. Sometimes they are referred to as Double Glazed or upvc window handles due to the popularity of this handle over the years and its wide use by uPVC window manufacturers in the UK for double glazed windows.
What is an Espag Window Handle?
These are replacement window handles for uPVC or any window with a multi-point espag lock (turning the handle turns the locks down the side or the bottom of the window). There have been many designs over the years but the good thing is they have kept the replacement criteria the same as long as you have a 7mm square spindle and the fixing screw centres are 43mm then you can choose from the large range available. A range of Espag door handles is also available.
The popularity of this type of handle has led to much innovation in the styles and the functionality of the espag window handles range, offering much in the way of choice for the style or budget conscious customer with a range of designs and colours.
Cranked Espag Window Handles
The term cranked simply means an offset lever design and from a functional perspective the benefit is more generous hand clearance against the frame. This is particularly helpful where the espag handles can be right up against the edge of the frame making it difficult to manipulate the operation of the handle, so the handles are offered as a left handed crank or a right handed cranked design depending on the orientation of the window. When fitting to the window the cranked design must be the correct handing and this can be identified as follows: handles that open anti-clockwise are right handed and handles that open clockwise are left handed in all cases.
Espag uPVC Window Handles 50mm Spindle
The nature of the design of these handles is such that a spindle (7mm square) protrudes from the back of the handle and enters the window to engage with the gearbox of a multipoint locking system. Depending on the size and design of the window will then determine how long that 7mm square spindle needs to be in order to reach and penetrate the lock system inside the window, which is what it must do. Over the years many types of windows have used the espag handle design and even though some sizes are more common than others it is possible that you can have any size between 10mm and 60mm in some cases. Aluminium windows tend to use 9mm, timber windows tend to use 30mm and upvc have used all other sizes as the frames can vary in size although 40mm is the most popular.
