Window lock for Okna Casement 4700 series

I am looking for a lock that I can secure on my existing okna casement window to prevent my son from opening the window.

Can you please advise on a product that works for this window ?

Thanks in advance,

Hi Mike,

Thanks for the information. The video illustrates the locking mechanism for a double hung window. Can you please confirm if this lock will also work for casement windows ?

Thanks in advance

It was no problem at all, Malar! I was happy to help. I actually do not believe the 26-387 would work for a casement window. It is not recommended.
