Channel length is 26 inches

Check me.... is it product code S385-26 with option code 2540?

Thank you! I'm glad we're able to help. Now, the S385-26 looks close, yes, but just make sure that the size of your shoe matches our 15-004, which is what the S385-26 comes with. I also agree that the 2540 option is correct.
