Channel Balance Help

Question

I do not know the manufacturer of my windows and cannot find it labeled anywhere on them.  I need to replace this window sash.  In addition to picture above, it has a label of UB 23D.  Thank you

Is the metal channel 23" long? If so, take a look at our S770-23. Carefully look over all the specifications listed to see if this matches what you need. You'd need a stamp option of 23D.
