Channel balance and sash guide

Thanks for writing in. I agree your Top Sash Guide looks like our 18-161. As far as your channel balance, start by viewing our S380-30 or S385-30. The only difference between these two balances is 'depth', or heel-to-toe measurement of the bottom nylon shoe. For the Series 380 the shoe depth is 1"; for the Series 385 the depth is 1-3/32". Compare both with your old hardware to see what matches best; if you're uncertain, let me know the depth measurement of your balance's nylon shoe. In any event, you will need a stamp option of 2930. Let me know if you have any questions.
