Identify Window Channel Balances

Channel balance is 29"x1/2" with 2820 stamped on it. Looks like it most closely matches your S351 except my shoe and top are white. Please advise.
Thanks,
John

Hey, John. As long as your bottom shoe depth is 1", then the S351-29 looks like a good match. The color doesn't have any bearing on function.
