Pivot shoe removal

Hmm... before we start making any cut-outs, can we see a few pictures of the track itself? If we can take a look at it, we can determine whether or not you could use a heat gun or hair dryer to soften the track.

Ah yes, I see what you mean. Alright, I think at this point you might want to consider creating cut out yourself. Since you're working with the bottom sash, I would make the cut out at the top of window channel. Now, making your own cut out isn't the most recommended course of action. There is a chance you can cause damage to the window or you might even hurt yourself. It's really a last-ditch project when all other options have failed. If you choose to do it, make sure to be very careful. You are cutting rigid vinyl and safety has to be paramount. It might be best if you have a local handy person familiar with this kind of project come out and do it for you.

After you get the pivot shoe out, check the dimensions. It could be either our 15-047 or 15-121.

Great news! Glad to hear everything worked out.
