When I measured the Unbroken Top Sash, it was approx 2.4cm = 0.94 inch across.
It seems a good part would be PGT TOP SASH GUIDE(Product Code: 18-015) but I wanted to confirm with you.
Thanks.

I'm afraid I can't confirm if this is our 18-015 based on this picture. You will need to remove an unbroken top sash guide and carefully compare its style and dimensions to those we show for the 18-015.

Finally, was able to open the window and measure the top sash.
I went ahead and placed an order(for 18-009) ahead but unfortunately, the top sash screw hole didn't line up.
I need a top sash guide of same width as 18-009 but slightly longer

Looks like you might have a Kinco window. Please compare our 18-166 top sash guide to yours.
