Window crank

Hello, Christian. I've seen this operator many times before. This is not something we can supply; I suspect it's not made anymore, but I admit I'm not too sure. It is an older design, indicated by the squared-off base style.

The best option in our inventory, as far as alternatives go, is the 39-172. This will fit in your window without issue and works more or less the same way, but my major concern is the offset in the link arm. Ours is a lot more dramatic than yours, and that may hinder how the arm connects to the sash bracket.

I've never tried it myself, but at this time the 39-172 remains our best and only suggestion for this window. I am sorry we can't give a more confident recommendation.
