Help me to identify the right balance

Question

I need 8 pairs of these balance. The part number is showing in the picture. They show different numbers, but they all actually look the same to me. The two plastic ends look the same. Can you help me to identify which part I need to buy? Thanks a lot!

Your balance closely resembles both our S380-30 and S385-30. The only difference between these two balances is the depth measurement of the bottom balance shoe. The depth measurement of the bottom shoe is 1" and for the Series 385 is 1-3/32". Measure the depth of your bottom shoe, like in the diagram below, to determine which balance would make a better match. whichever one chosen will go with the 2950 option.
