Hi all. I'm looking for advice. My rental has vertical blinds and I want to add sheers. I noticed that the existing hardware has this track a the front. The track is metal, 2.5 tall with a 3mm lip on the top and bottom. I have no idea what it's called or typically used for but I'm thinking it might fit clips or a pole bracket.
What can I buy that will fit in that groove and let me add sheers?
Thank you!
P.S. Please excuse how dirty they are!
Right hand side of the vertical blinds.
