Hello!

When I took my window apart, it was missing the part in the pictures above on one of the sides. I need an identical part. Could you help identify which part number I need to purchase?

Thanks for writing in. Make sure that the metal channel, not including the nylon fittings, is 15" long. If so, see either our S380-15 or S385-15. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what the best match is. You will need a stamp option of 1440.
