Thanks for writing in! Your channel balances appear to be either our Series 351 with 1" shoe or our Series 390 with a 1-1/8" shoe. To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe.

Once you've confirmed the series, you'll be able to select your stamp option. For the 28" balance you'll need to select the 2720 stamp and for the 29" balance you'll need to select the 2820 stamp.
