I have some balances on some wide sashes stamped 2590 30. The largest you show is 2570. Can you quote a 2590? I will need 3 of them

Hello there. That stamp of 2590 is from an obsolete rating system. Weigh the window sash these balances support. On the S351-26 shop page you'll see a chart that lists the weight range associated with each stamp option. You can use that chart and the exact sash weight to choose the right stamp option. Let me know if you have further questions.
