Identify balance. Pics attached. 24xhd

Thank you for reaching out to us. It seems you have a balance similar to our Series 751. It appears in the photo that your balance measures 25" in length according to the measuring tape next to it. Is that right? If so, take a closer look at our S751-25. If this is right, you will go with the 24HD option that holds a sash weighing 18-22 pounds. Look it over and let us know if you have any further questions.
