Hello there. When the 'inner guts' of these balances break down, they need to be replaced entirely. Fortunately this is pretty straightforward. This looks like either our S351-28 or S390-28. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You'll need a stamp option of 2740. |
