Tilt Latch for old Mastic tilt window

A quick learner from Hatfield MA says:
What tilt latch do I need? Please refer to attached photo.

The measurements are

2 3/4 inches long
1 1/2 inches wide
1/2 inch deep

Which tilt latch do I need? The 26-111 seems too long.

How long is the 29-111?

Hello! You can see the dimensions for the 26-111 on its store page. I'll also post them here for your convenience.

Like you surmised, this appears to be too long. None of our other dimensions seem to match, either. The bad news is, I couldn't find any other latch that meets your specifications. The 26-111 appears to be our closest match, though if your measurements are accurate then I don't believe it will work for you. I am sorry we cannot offer a better option.
