Certainteed lock

The handle broke off of this latch. It has Certainteed on it. I need a replacement. The one I found on your site it too small. I also struggling to remove it off the window frame even after removing the 2 screws. The overall lengthof the base that screws to the sliding window frame is 3.375in, center to center of the 2 screws is 1.5 in and the handle is approximately is 3.25 in outside to outside at the pivot end. The base is about 1.5 in wide horizontally.

Thanks,
Wade
