This T-Lock Shoe looks like our 15-195. However, note that your old T-Lock Shoe has a 'groove' in the stem, that interfaces with a similar indentation in your existing channel balances. Both our T-Lock Shoes and the corresponding balances lack this feature. Therefore, I'm afraid you'll need new channel balances outright. See our Series 795--note that the 15-195 comes installed by default with these balances, so there's no need to purchase them separately. You can read more about the Series 795 here.
