28" Channel Balance - 2730 Stamp

Question

Greetings,
The metal portion of the Channel Balance is 28". The stamp is 2730. I would like to replace both Channel Balance of the Alenco window.

Hey there. This looks like an S351-28 or S390-28 Channel Balance. The difference between these two balances is the 'depth' of the bottom shoe. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2730.
