I have an older crank out, outswing Milgard window. In the frame it has two different weatherstripping. One is slid into a square channel. I need to replace this. Attached are pics, one of which is the label in the window. The other 3 are of the weatherstripping with side view, both sides and cross section. The portion to the left is the portion that slides into the square channel. I cannot find anything similar to this. Thanks for your help.

Hello,

Unfortunately, we don't carry an exact replacement for your weatherstripping. Our best option would be the 58-170B but we've gotten mixed reviews from past customers with similar seals. Look over the product images and specifications to see if this might work for you. Thanks for posting.
