I am having a hard time finding an exact match for this window sash balance. I have found some similar ones but none with quite the same bottom cam. I would be grateful for any help

Thanks for writing in. See our S380-30 or S385-30. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your own hardware to see what matches best. You will need a stamp option of 2950.
