Door Handle Springs (2.5-turn coil, 2.5mm thick) for internal door handles. Can be used on both right handed and left handed handles. Spring dimensions are shown in the additional photograph. When replacing a door handle spring the two most important things to check are a) the orientation of the external hook compared to the internal hook eg. is it a 2-turn coil or a 2.5-turn coil and b) the thickness of the spring when laid flat. Most springs are retained with a circlip, which can be removed and replaced using circlip pliers. Circlip pliers are available quite cheaply on Amazon or in repair kits on the Northern DIY website. The 2.5-turn, 2.5mm thick coil shown here is the most common type of door handle spring. Please note that if you fit a thinner spring than originally fitted the handle will have some excess play. If you fit a thicker spring than originally fitted it may be difficult to replace the circlip and the handle may have a tendency to stick.
