Looks like the series 751 ribbed channel balance. Measures 19" along the channel but unit is stamped s 18HD. This is for a weathershield double hung tilt window.
Just want to be sure and order correct part.
Thanks, Randy

It's normal for an S751-19 to be stamped with 18HD. I'm afraid I can't confirm if this is what you have based on just the information you gave us, though. As long as your hardware looks the same as our pictures, and all the information we have matches up, then there's a good chance it's what you need.
