Hi -Just bought a house with Kolbe crank windows. I'm looking for a folding crank to replace the existing ones that 'stick out'. Does such a beast exist?

Hello there!

Thanks for reaching out to us. We may be able to help with this. Can you upload a photo of the crank handle you have now? We'd also like to see a photo of the window open so that the arms that move the window sash are fully visible.

Hi Emily - Please see attached 3 pages. Hopefully they are self-explanatory.

HI Emily - Please see attached 3 pix. Turns out my house has 2 types of window cranks (one with a removable gear cover; the other is not). Both seem to share the window opening mechanism, which makes me think they are the from the same manufacturer (Truth).

Great, thank you! Truth brand operators have a 11/32" spline which is compatible with the 39-205 folding handle. Take a look at the specifications and let us know if you have any questions.
