328 HK5 CMC4 balance

Thank you for your post. Have a look at our S795-32 channel balance. This comes with a 1-1/4" wide T-lock balance shoe. It also includes a clip on the cord that is screwed at the top of the window track. Take a look and see if this is compatible with what you have. If so, then you can go with the 32B option that supports a sash weight of 14-20 pounds.
