Greetings.
I’m in search of some cross referencing assistance with replacement balances for Pella DH units from the 90’s (a great period for music but apparently not for Pella Windows). Suggestions welcomed.
The black plug slides into a hole in the side of the sash and is held in place by a screw that also attaches the cord to the sash. I’m no rocket surgeon but I’m fairly certain an outhouse is a more high tech design than this.
Pella balance help.

Hello, thank you for posting,
Your channel balance resembles the Series 745 that uses a terminal plug. Please confirm that the length of the metal channel measure 26-1/4" long.
The 3660 stamp does not directly translate. To further review, we will need to know the weight of the window sash that these balances support. The sash will need to be removed and placed on a bathroom scale. Thank you!
