Iwc window latch

Thanks for reaching out to us, Tony. We don't sell this exact lock as it's no longer made but the original manufacturer suggests the 90-313 as a substitute. Just note, you would need to re-drill new installation holes and use a screw like the 33-011. You wouldn't want to use too long of a screw, and be careful not to drill too deep, as you could damage the frame or the glass in the sash.
