Which Option for my Channel balance?

Quick Learner from San Jose, CA
Hi,

I know that I need a 26" Series 351 Channel Balance but I don't know which option (2510, 2520, 2530, 2540) to order.

Looking at a past similar question and your answer, I can tell you that my widow sash is about 14 pounds (I don't guarantee the precision of the scale).

Which option should I order?

Looking forward to reading from you,
Regards,
Eric

The S351-26 with stamp option 2520 is designed to hold a window sash weight range of 9 through and including 15 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.

Hi Donna,
Thank you for your answer.

As I said, my scale is not that precise and at 14 pounds, I'm close to the limit of the 2520 option.

May I know the range of the next option?

Looking forward to reading from you,
Regards,
Eric

Hi Eric,
The 2530 stamp option is the next weight range; it will carry 15 through and including 19 pounds.
