TOPP C20 Electric Chain Window Operator 230VAC - White

Category Manager

Hi, Thank you for your question. Unfortunately it is not as simple as being able to give a maximum size of window as it depends on the force needed to open the window, of which there are several factors to consider. There is a calculation to work this out though and I have attached an image which shows this, sizes are in mm. For reference the maximum force this unit can handle is 300N and the operation stroke is either 240 or 360mm, I have also included an image showing what height window you would need to be able to achieve those stroke lengths. I hope this is of help and if you need any further information just let us know.
