Need parts for double hung winows

NAMI sticker code: S-082-1

NAMI sticker Rating: H-R50

NAMI sticker series: 1850 DH

NAMI sticker MST: 3850

We believe these are manufactured by Superseal Manufacturing which has been sold to Hurd, who sells this line under the Sierra Pacific Brand, 8000 to 8500 series.

However the new line does not appear to share the same parts inventory.

I am hoping to get parts to replace the disintegrated parts in the attached photos.

All help and instruction is appreciated

yes I need the 15-216 parts (quantity 8) as well as the small bar that comes from the bottom of the window and inserts into the 15-216.

Is there a diagram I can consult because I do not know the names of the various parts. ie, what is a metal channel balance?

I think that the collar that connects the cable to the 15-216 needs replaced as well.

Thank You

John
