I need to order some 9/16" wide window channels for non-tilt windows. The model #'s are 1620 ans 2230. I believe it's the 350 series, but would like you to confirm before I place an order. The bottom plastic part has a plastic slider on both sides and the top has no plastic sliders. I attached a few pictures. Two pictures with the plastic clips are the bottom and the top is the picture with no clips (plastic sliders on the sides).
Thank you,
Ed
