Series 395 28" channel balance

Question

I'm looking to order 28" series 395 channel balance but the stamp on my old balance is 2790 and yours only goes to 2770. Is this going to work with my alenco double pain insulated window .

Thank you for reaching out to us. I am afraid there is no modern option that corresponds with a channel balance stamp ending in "90." That is an old strength rating system that has fallen out of use. We recommend you weigh your sash on a scale and refer to the chart on our S395-28 channel balance store page to confirm the best match for you.
