Read other posts on your site. Hopefully I have included all the info and pictures you need. Thank you for your help.

I need two sizes; four of each size.
The metal channel for both sizes are 9/16" wide, 5/8 deep.
The foot is 1 1/8" deep. The top and foot are the same for both sizes.

Thanks for posting. For the 22" long balance, see our S390-22 with a 2170 option. Two of these balances can carry a sash weight of 34 through 37 pounds.

The 28" long balance would be our S390-28, but it will need to be custom made with a special 2780 option. I would be happy to send you an order link and price quote, but first I will need to know how many of these you need.
