Thanks for choosing SWISCO.com. We would love to help, but we need to see photos of the balance, especially the two ends. Once we know the series, you will select a 28" length with a 2740 option.

Thanks for the photos. I am leaning towards our S395-28 channel balance as a match. Take a look and see what you think.
