Andersen Sash Balance

Question

Hi,

I need to replace 7 Andersen sash balances.
Old balance #s D5 7 27 12 70
Purchased one new balance #737, is this the correct balance to replace the old balances with?

Thx,

Scott

An old Andersen balance with a stamp code of 727 can indeed be replaced by our 24-737. The only issue I see here is that it appears your old balance lacks that side tab that our replacements possess. This is common with older versions of this hardware. You'll need to chisel out space in the window frame to accommodate the tab. The blog article here goes into detail.
