balance

Good question. Recently, some of the crossbow balances have become discontinued and unfortunately, the length you are asking for was one of the sizes that is no longer available. We suggest going with our S795-30 balance with either 1-1/4" wide shoe or the 1" wide shoe. To choose the option, you must weigh your window sash on a scale and take that weight number to the sash weight chart listed on the product page. You will also need to replace your current pivot bar with our 26-021, most likely.
