IWC Window latch

Hello! Thanks for getting in touch with us. I do recognize this window lock, but I'm afraid that it's no longer made. The original manufacturer recommends using our 90-313, however. They inform us that this works well as a substitute, however it will be necessary to remount the installation holes at the top. We recommend using a screw like our 33-011. Just be careful when drilling not to hit the glass.
