Channel Balance Stamp Options

Hello! If your original stamp doesn't match any of ours, then the best way to determine which of our options will work is to weigh the window sash on a scale and pick from our weight chart.

For your reference, the stamps available for the S751-25 are as follows:  

• The 24R will carry a sash weight range of 10 through 18 pounds
• The 24HD will hold 18 through 22 pounds
• The 24TG will hold 22 through 30 pounds

24Q is unfortunately not a stamp that I'm familiar with. I think the safe option would be to weigh your sash on a scale, as described above. If your sash weight falls within the 10 through 18 pound range, then the 24R stamp will work perfectly well for your application.

No, the K in your stamp shouldn't mean anything essential. I believe that our 24HD stamp will suffice in this case, but you can always weigh your sash to verify.
