Hello, I have Alenco windows installed in the mid 80's and need a cam lock like this one pictured.

Thank you for reaching out to us. Based on what I see in your photo, I recommend taking a look at the 90-025 window lock and 90-108 keeper. Carefully review the specifications for these parts and compare them with your old hardware to see how they match up.
