20 year old IWC windows

A professional from los angeles says:
I need to replace my IWC window locks as well as my tilt latches. The locks have the IWC logo, a product number SP2203 and a patent number DES 432,900.
The tilt latches are 3 1/2 inches in length, 7/8 inch in width, are 1/4 inch thick, and the two attachment holes are spaced 2 5/8 inches apart. Any assistance with potential replacement parts would be appreciated.

thanks...jeff d.

Hey Jeff. I'm not certain without pictures, but if the IWC lock is like the one in the picture here, I'm afraid it is no longer available. However you may be able to replace it with our 90-313 sash lock. You'll have to remount the holes at the top use a screw like to the 33-011. You don't want to use too long of a screw, or drill too deep, as there is a risk of damaging the frame or the glass in the sash.

The tilt latches might be our 26-193 and 26-194. Compare the dimensions and see if you agree.
