Frequently Asked Questions

Is the KATO KS30/40 right for my windows?2023-07-24T15:32:48+01:00

The suitability of an electric chain window actuator will depend on a number of things including the type, weight and size of the windows or openings, the property itself and how the window is going to be used.

For example, a single, small residential window may not be suitable for the brackets supplied with the KATO KS30/40 and would be better suited to a different model. However, those looking for something with remote capabilities or simpler wiring configuration, then this window actuator could be the ideal solution.
