I use up to
80 of these a year. The manufacturer I used before went out of business and I need to buy more of these balancers.

Thank you for your patience during this busy season. Your balance appears to be a match for our S390-27 channel balance. This has a 27" long metal channel, as well as a 19-002 top fitting and 15-001 bottom fitting. As long as those fittings are the same size as the originals I'm confident it will work.
Additionally, you should weigh your sash to confirm the best weight option. Your stamp indicates a 37 pound sash, which match our 2670 stamp, but I still recommend weighing the sash to be 100% sure.
