IWC Latch

Hello,

I'm afraid that this IWC Sash Lock is no longer available but the manufacturer recommends using the 90-313 as a substitute. However, it will be necessary to remount the holes at the top. 

To do this, you will need to use a screw like our 33-011. You don'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. Thanks for posting!
