Do you stock this screen knife latch?

Dear Sir of Madam:
Find, attached to this message, a drawing of a screen knife latch for the picture window in our living room. I tried to take a picture of the latch, but our lousy camera cannot take close-ups. The manufacturer of the window is unknown, but "Entry-Gard" is stamped in the mechanism that opens the window. It looks very similar to a part listed on your site (Product Code 70-172), but the measurements are significantly different. Furthermore, unlike your part, note the dimple that is located in close proximity to the block-C cut-out.
Sincerely yours,
David S

Hey, David. I'm afraid this latch might not be available anymore. Your screen frame could be an older, wider profile, which would account for why your clip is a little larger than our 70-172. We do carry the 70-174, which was used on older Andersen screens, but that looks like it would too large. Could you use a face clip like the 70-197? Let me know what you think.
