Looking for confirmation on the style before I place order... length is 29"
Not sure if the top attachment and shoe attachment..
Stamp on the rail looks to be 2830Z. I see online the 2830 is for Sash weight of 16-23 lbs...... not sure what the "Z" at the end is for.
Thanks for your assistance.

Thanks for posting. Please take a look at our 29" Series 370 balance. Compare your measurements to ours to confirm this. You'll want to select spring strength option 2830.
