Hello, I am checking if this is something you can furnish, looking for price and availability of about 10-12 pieces.

I'm afraid that this window lock is not familiar to us. We would like to see it removed from the window, if you can. Please send us some photos of it by itself. We will also need your measurements. There's a chance it's no longer available, but maybe we can suggest something else that could work.
