Thank you for your patience in this matter. It appears that you will need a custom-made balance with our 15-001 shoe and 19-015 top. However, before we get started, can you please confirm that the length of your metal channel is 21"?

If so, please take a look at this Custom Channel Balance Order Form I have started for you. Please fill out the rest of the information and one of our representatives will be in contact with you shortly thereafter.
