Channel Balance Quote

Question

Hello,

I am looking at your S380-27 on your website, but the stamp on my channel says 2690.
Which option should be chosen?

Hello there. The stamp code 2690 is from an old rating system we no longer use. To know what stamp option to select, obtain the exact weight of your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the shop page.
