Part Number for Window Hardware

Thanks for writing in. For the channel balance, it appears you have either the S380-25 or S385-25. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Compare both with your old hardware to see what matches best. In either case, for a stamp option choose 2440.

For the Viking window latch, start by looking at the 90-278. Compare all the dimensions listed below with your old lock, and let me know if anything differs. 

Finally, I'm afraid I'm not familiar with the Milgard piece you show. Can you show me where and how it installs in the window? Can you tell me its basic function? Pictures from a few different angles and some dimensions would also be great. From there we'll do our best to see what we can find for you.
