Mileston single hung series 1000

Question

Windows are Milestone single hung series 1000. Window just falls shut, I am assuming because the channel balances are broken/old. Please advise. The balances I removed are 29 inches, measured as instructed in your video. I have attached pictures of the top and bottom plastic pieces. The balances have a large spring, two small pulleys and a string, I am unsure how they were oriented. Only markings are an imprint of 28E. What replacement channel balances do I order? Thanks.

Thank you for contacting us. Depending on your balance shoe measurements, you will either need our S380-29 or S385-29 channel balance with a 2850 option. Take a look and get back to us if you should need any further help.
