Non-tilt window channel balances

Question

Width is 1/2" commercial (actual 9/16")
Length is 31"
Marking states 30XHD

I also have the same exact type but shorter length that needs identifying.
Marking is 24XHD
Length is 25"

Thank you!

Please start by looking at our S751-25 channel balance. You may also need a new S clip, so see our 19-030. The balance stamp option you need could be 24HD but weigh your sash just to confirm.
