Question about Stamp option and attachment

Hello,

My window weight was about 18.5-19 lbs, I was wondering since this weight was so close to the 2730 and 2740 stamp option, which one would be a better choice. I did notice it saying "27 4 Caldwell BM", which I assume would point to the 2740 option.

Additionally, I have attached some photos of the top and shoe attachment to verify if this is the correct product for me

Thank You, Neil

If your balances are stamped 2740 and have been working properly up until now, I'd recommend sticking with that spring strength. Please let us know if you have any other questions. Thank you!

I do in fact agree with your recommendation of the Series 350, Neil. Looks like you picked yourself a winner.

Hello,

I have attached some photos of the top and shoe attachment and wanted to verify if the series 350 channel balance is the correct product for me.

Thank You, Neil
