Roto locking handle for a casement window

Hello,

We'd be happy to look into this for you but we would need to see photos of your original casement lock removed from the window. Written-out dimensions are also helpful. In the meantime, you are welcome to look through our selection here. Thank you! 

Unfortunately, we do not carry a suitable replacement for the locking handle shown in your photos. I would recommend reaching out to a Roto supplier directly to discuss your replacement options. 

I'm sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions. Thanks for posting.
