28D balancer

Thanks for reaching out. It appears you have the S795-28 Channel balances with a 28D Stamp. These come equipped with a 1-1/4" closed cam, T-Lock shoe. 

Also, this balance has a screw tab on top so, if your balance has a screw tab, you can just purchased the balance as is. However, if your balance has a hook attached to the top, please let me know as that will need to be a custom order.
