I have a window balance that has 29 2 stamped on it. It's 30 inches and has the top is definetly 19-018 and the foot is the 15-005. I'm looking for some replacements.
Hello,
The channel balance Series 377 has the needed attachments.
The 29 2 normally translates to 2920 stamp option. To check, remove the window sash and place it on a scale. 30" Series 377 Balance with 2920 stamp option will carry a window sash weigh range of 12 through 16 pounds.
This information is based on 2 balances per sash. Non-tilt block and tackle channel balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
