Channel balance

Hello there. I am afraid I don't recognize this part at first glance. Can you show me where it installs? What is its function? We'll do our best to help from there.

Thanks for getting back to me. OK, this is a Face Guide, which does exactly what you described. I am not sure we have this exact version you show, but see our 67-014, which snaps into the frame, as well as our 67-002, which attaches by screwing on. Take a look at both guides and let me know if you think either might work for you.
