Hi, Mike. Your balance looks like a match for our S900-18 3/8" diameter tube spiral balance. Your white tip color option was phased out a while ago and replaced with one of the modern options. I recommend weighing your sash and referring to the weight chart on the S900-18's store page to determine the best choice. For the spiral balance charging tool, see the 75-006. |
