The the nylon attachments are the same as our Series 350 channel balance, then that's what I would go with. The option is based on your stamp, though I don't recognize yours. You will need to get the weight of your sash and compare it to the chart we show on the S350-32 store page to determine what will work. You can determine the weight of your sash by simply removing it from the window and weighing it on a scale.
