I have 3 different sized windows.
1) Channel length is 25 5/8" stamped 25 5 (1 window this size)
2) Channel length is 31 5/8" stamped 31 5 (6 windows this size)
3) Channel length is 19 5/8" stamped 19 5 (1 window this size)
Millgard Windows, house was built in 2004 and I assume Windows are original.
Windows have a sticker H-LC25-48x78 / H-R25-48x84: Series 1510/ 1580 /1680. P.L #032-136
I am looking to replace all the balances.
There is one more part which I believe is called a sash cam. The part is attached to the top of the bottom sash and appears to keep the window centered on the balance. I only have one broken at this time but figure I should replace all of them. I would need a total of 16 of these.
