Thanks for contacting us! If you're talking casement windows, I recommend that you take a look at our 39-020 & 39-021 wood window cranks. They are fairly uncomplicated and I think they may work on your windows. Take a look and see what you think.
Keep in mind you will also need a track to go along with these cranks; see our 39-520, which works with the 39-020 & 39-021. You may also want to look at the installation instructions we have for these two operators. Take note that you will have to install the operator on the sill, under the wood sill cover. You might have to make a cut and notch the one you have. You may also have to cut down the screen in the height if you replace the sill cover with a higher one. It might be best to have a carpenter help you with the installation. |
