Window channels

A quick learner from Lakewood Ranch, FL says:

I think I ordered wrong (2840) it seems.

These are 29 inch long and 1/2 inch wide and has 28-C stamped on them.

From above would you please identify what part do I need.

Shoe is about 3/4

Thanks,

Bharat

Hello,

I can't be sure since the bottom fitting shown in your photos is damaged but your assembly reminds me of the S380-29 at first glance. I'd recommend removing an intact balance to confirm that the 1" deep bottom shoe matches yours. 

If so, your 28C stamp indicates that you would need 2830 strength options for your balances, which will support a sash between 16-23 lbs. Thank you!

Your balance does resemble the S380 but you would need to remove the balance fully to confirm that the bottom fitting measures exactly 1" deep, which, unfortunately, we can't confirm from photos.
