Pack of 6 coil springs plus 6 circlips for internal door handles. Can be used on both right handed and left handed handles. Spring dimensions are shown in the extra photograph above. Circlips are 13.8mm internal diameter (to fit 15mm shaft with 14.3mm groove). 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 (hosted by Amazon). 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. The circlips included are also the most common size used in door handles. When deciding on the size of circlip for your handle its better to measure the shaft rather than the old circlip as some poor quality circlips can become distorted.

Tip: When fitting a new spring a little grease will give better wear and movement.
