Balance is 31" but stamp says 30?

We need replacement for this balancer. From one end to the other it reads 31" but it says 30H. Can you provide me with the correct part number so I can place my order please? The only confusing part is that it's says 30H but the length is 31". Just wanted to make sure I order the right part. Thanks!

Thanks for your patience during the holiday season. I think we can replace this, but I'm torn on what to recommend. Can you confirm that the metal channel is 9/16" wide by 5/8" high? If so, I think you can use our S751-31 with a 30Hd stamp.

If your metal channel is different, though, then let me know. We'll need to do a little more digging.
