Marvin window balance; Series 751?

I have Marvin double hung tilt windows and need to replace a pair of balances. The old balance has 22 xhd stamped on it and is 23" long and is 9/16" wide with a ribbed channel.
Would the S751-23 be the correct replacement balance?

Thank You,
Grant

Thanks for posting in our Discussion Board, Grant! I agree with you, the S751-23 looks to be a very close match to your own hardware. You should also look at our 19-030 Long S-Clip.

Finally, please be sure to check out our tutorial video on how to install this type of balance. Hopefully this will help you get an idea of what you're working with!
