No part number on the piece. These are from paradigm vinyl double-hung windows. 1 5/8" tall, 3/8" wide. The back is 1 1/4" tall. Looking to purchase a dozen or so.

Hi there!
Take a look at our 26-362 vent latch. Review our dimensions and compare them to your current hardware to see if this matches up for what you need.
