Garage single hung PGT window

Question

Hi,

I'd like to order 2 pair of replacement sash levellers. The existing tube is 24" long. See the attached pictures.

Thank you,

Ed

Hey Ed. This looks like it might be either an S351-24 or S390-24 Channel Balance. The only 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 2350.
