5/8" Block and tackle non-tilt Window Balance - Stamp 25 3 KO Caldwell

Hi Greg. Start by looking at our S380-26 and S385-26. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so you're going to have to find an undamaged version of your old balance to compare and see what matches best. If the other balance in this window is undamaged, use that. If not, is there an identical window in the house? Chances are it's the same balance. Once you know what balance to select, choose a stamp option of 2530.
