I want to replace the channel balances in one of my windows. On the original channel balance the stamp only has the number 16 on it.
What do the option numbers for the S751-17 unit,(16tg, 16hd, 16r) mean? Can you suggest which option number I should choose.
Thank you,
Charlie

I want to make sure I order the correct balances for my windows. They were built in the 70's and have insulated glass.
S751-17 Balance
Window 1: W/H 20"X30.5", weight 12.5lbs, balance length 17", stamp 16
S751-25 Balance
Window 2: W/H 28"X38.5", weight 21.5lbs, balance length 25", stamp 24
Which option should I choose for each window? TG,HD,orR
For window 1: S751-17 (12.5 lb sash) choose stamp option 16R.
16R will carry a window sash weight load range of 10 through 17 pounds.
For window 2: S751-25 (21.5 lb sash) choose stamp option 24HD.
24HD will carry a window sash weight load range of 18 through 22 pounds.
This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
