replacement parts for milestone single hung series 1000

Question

My house, built in 2004, has milestone single hung series 1000 windows. The windows are difficult to slide up and down and with several of them if I open them I cannot get them all the way closed. It appears I need to replace the channel balances. After reading one post, it looks like I can use your S380-29 channel balance, but I am not sure of the stamp option. I am afraid to take the current channel balance out, for fear I will not be able to get it back in place while waiting on replacement parts. Is there any way to estimate the stamp option based on window dimensions?

There are only two ways to determine what stamp option you need for your balance: you can either match it up to the stamp currently printed on your balance, or you can weigh your window sash on a scale and cross reference the weight with the chart found on our S380-29 store page.
