Need channel balancer for mid-80s Milgard window

Home Owner from Seattle area
1/2" channel balancer, 21 inch channel length
1-1/8 inch bottom shoe, no ears on either top or bottom shoe
Channel stamped with "20 D" and what may be "BSI" (very small)

See photos.

I suspect I need a 21-inch model 390 / 2040 balancer, but I figure I should ask.

Hello there! I agree, I think our S390-21 with a 2040 option appears to be the best choice for your application.
