Viking Channel Balance Stamped 1490 BSI BL 16

Question

Non-tilting single hung window, installed in 2002. Pretty sure I remember they were Viking windows, although I can't find any markings on the window itself.  Balance is stamped 1490 BSI BL 16. Fell out on it's own, so no pics of it installed.

Hello,

Take a look at our S395-15 channel balance. Unfortunately, your stamp that would normally indicate the spring strength needed to support your window sash is outdated, so I would recommend weighing your sash and following the chart under the product description to choose to correct spring strength option for your balances. Thank you!
