Searching for SP2203

Unfortunately, this IWC sash lock is no longer available. The original manufacturer recommends using the 90-313 black sash lock, though it will be necessary to remount the holes at the top. You will need to use a screw similar to the 33-011. You don't want to use too long of a screw or drill too deep, as you could damage the frame or the glass in the sash.

You could send your photos to help@swisco.com. The customer service reps who monitor that account will ensure that I get your pictures.

That said, photos at this stage may not be necessary. If you have the same IWC lock as shown in the photo above, then our 90-313 remains our top alternative. I know the design is very different, but they function in a similar manner. You just may need to drill new holes for the new style to install.

There are no other alternatives at this time, unfortunately. The 90-313 is explicitly recommended by the IWC manufacturer as the best possibly replacement at the moment. I don't think you'll find anything closer.

The screws are on the back side of the window frame, obscured from view as long as they're installed. If you were to tilt in the sash, as if for cleaning, you'll be able to access them.
