A home owner from Easton ,pa. says:
Hi
The Channel Balance that I need, looks exactly like the one in the S795-21 product picture on the web site. This is the size I need but mine has no letter stamp. only stamp is 20 09 . I have no idea of what option to choose.

Please remove the window sash and place it on a scale.
We need the weight of the window sash in pounds to determine the proper stamp option.
