2790 31 is the numbers on the channel. Length is 28" metal only. width is .5 "
Hight is 5/8". I realize this may be a custom channel. Do you think the 350 series 2770 channel will work. I think I need the "Comes fully assembled with the 19-002 top and 15-004 (1-3/32" deep) bottom fittings and will be ready to install out of the box." too.

Thanks
Nico

Hello,

I agree that the S350-28 channel balance would be the correct replacement but you'll need to weigh your sash and follow the chart under the balance product description to choose the correct strength option. The 2790 stamp on your balance is part of an outdated weight system, so the sash weight is the only reliable way to make sure that you order the correct repalcement. Thanks for posting!
