Non tilt ESP

A quick learner from Hilton Head Island SC says:

Stamped as 2780 BSI 28" length

These break after professional fixed! Do we need larger weight rating?

Thank you. We need to order multiple pieces but want to get the correct parts with your help

Thank you, John C

Hello!

Do you have any of the original balances? Just in case it's a different series.

Your channel balance looks like it might be our S390-28 with a spring strength option of 2780. A pair will carry a sash weighing 42-45 lbs.
