hello, pls could you tell me the full owning distance of the window crank for use on an awning window. The maximum load it can support and if there are any technical drawings available for the 39-015. Thanks for your help, Steve

Hello, Steve! I'll do my best to help.

The 39-015 Roto Gear Window Crank Awning Window Operator has an approximate sash opening of 14 1/2". I unfortunately do not have a maximum load for this awning window crank operator on record, but it's viable on most residential windows.

Take a look at the included picture for a more detailed drawing of this window crank operator.

I own Anderson awning windows. Right now they only open about 8 inches. I don't get any air flow...will this operator work with my windows?

Awning windows normally don't open too far. With that being said, the 39-015 could get your window to open up a bit farther. Just note that you will need to have room to install it in your window.

I will say, speaking from personal experience, that you might run into problems while trying to convert the Andersen operator over to a Truth operator. I have never personally tried it, but if you do, don't forget the brackets 39-170 and the 39-114L handle. Those parts will also have to be replaced.
