Pictures attached of 17" long lift with "winged" top and bottom. The window weighs 15lb-9oz. I also need the channel balance guides, also pictured. I believe the correct numbers are S385-17, option 1640 for Channel Balance and the Guides are 18-178. Please confirm my selection. I will be needing 8 channel balances (4 windows) and 4 guides for same.
Thank you, Richard S

Hi Richard,
I agree, this is the S385-17, with stamp option 1640, and the 18-178, Top Sash Guides. The only thing I would recommend, is checking each window for the balance length and stamp. Windows in the same home often appear the same size but are not always.
