All polyplastic window fittings are available in either a standard screw-on fitting or the more recent variant of the slide-on Polyfix design.
 
The slide-on Polyfix design are easily recognisable by the deep grove moulded in to the back of the window fitting. It is this that slides over the adaptor fitted to the window.
