I believe I need to get the 9-15 lb. balance but want to confirm before ordering. Please help!

Hello there. This looks like either a Series 380 or Series 385 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. See the video below to determine the right length and stamp option.
