The pivot end is marked with 4610106
The part matches your catalog item S795-28, option 28B except it has a hook on the end opposite the pivot.
I need four complete channel balance assemblies like the one pictured.

That looks like our 15-198 clip. We can custom make this balance for you, but first I would like you to confirm a few things.
First, please send us a picture of the shoe at the bottom of the balance so that we can confirm that it is the standard Series 795 channel balance. I would also like you to confirm the stamp. In your post above, you mentioned the 28C stamp, but also the 28B stamp. Which of these is the correct stamp?
The part stamp is 28C.
The shoe is stamped with the number 4610106.
Thanks,
Joe
Great. I'll go ahead and email you a purchase link and price quote for your review.
