Roto Casement Window Lock handle

 Hey there,

Thanks for posting! The ROTO casement window lock you have here was discontinued back around 2013, unfortunately. To date, we have not been able to source a suitable replacement for it, so I am not confident it is available anywhere.

Our sincerest apologies that we cannot be of help with this repair but please don't hesitate to reach out with any other hardware repair questions you might have.
