does the drive "fit" or not? Comparison with the help of a two-euro coin

One of the criteria should certainly be the size. Especially when retrofitting facade windows in residential areas - but not only there - the size of the drive is often neglected. We have taken the trouble and photographed the most common drives for comparison with a 2 euro coin. The sizes are all true to scale and give you at least a visual impression of the sizes of our chain drives.

Please also remember that (almost always) every drive needs brackets. These often also ensure that considerably more space is required. You will find details about this with the respective products in our store.
