Broken T-lock for double hung windows

Hey Steve, thanks for writing in. Not to worry; you can tell these are closed cam T-Lock Shoes simply because you cannot 'see through' the metal cam; e.g. it has a back wall. So these T-Lock Shoes match the configuration of our 15-195. However, I'm afraid there's a problem here. Your T-Lock Shoes have a characteristic groove in the stem that configures with a similar groove shape in our existing channel balances. I am afraid, however, that our T-Lock Shoes lack this groove. Therefore, you'd need to replace not only the T-Lock Shoe, but your old channel balances as well. 

The good news is that the 15-195 comes by default with our Series 795 balances, which are the replacement balances you would need. If you need help identifying the right length and stamp options you need, send us the length of the metal channel for each set, as well as a picture of the stamp code on that metal channel. 

Also, how do your channel balances attach to the window track? Our Series 795 balances use a screw-on tab; however some versions of this balance have a hook instead that attaches to a slot in the window track. If your balances have a hook instead, let us see a picture of the hole in the window track where these hooks attach to. That will indicate the best course of action to take. Many thanks. 

Fair enough, Steve. Let us know how you make out. Best of luck with your repaiir. We'll be here if you need us! 

Welcome back Steve. No worries on the delay, believe me, I understand. If the balance's metal channel is 26", if it uses a screw tab, and the shoe is our 15-195, then you are fine just buying our S795-26 with a stamp option of 26C. The 15-195 is the shoe that comes by default with these balances. Spare 15-195 shoes you can of course also buy separately. But both these items you can purchase right through the online store. Let me know if you have any other questions.
