The only marking is on the channel "28C." This is from a double hung, tilt inward, window. The chord on the pulley system inside the channel broke so I am looking to replace.

Hello! Thanks for your patience during this busy season. Your balance appears to be a match for our S775-28 at first glance, but look it over and see if you agree. Make sure to measure the length of your metal channel first to ensure that it's also 28".
