My windows take 29" 385 series channel balance with 2380 stamped on it. I'm trying to figure out which top sash guides these are, or if there is a suitable replacement.

We don't have a Top Sash Guide with that insulation on the side, but you still might be able to use one of ours as a replacement. See our 18-127 , 18-166 , or 18-188 . Look over these options and see if one of them match up.
