Screen Knife Latch

Question

I don't have the model number from the window, but need help identifying this screen knife latch. Also need to replace the plastic piece that holds the latch in the slot of the screen frame.

Your knife latch reminds me of the 90-227 Large Butterfly Latch. To determine if this is the right replacement, carefully look over the diagram below.

Regarding the plastic piece you mentioned, may I see a photo of it. Unfortunately, I am not able to confirm a replacement based on the description alone.
