Knife lock custom configuration

Home Owner
I am trying to locate balances for my windows. I have multiple sizes that I need. Please help me identify the parts so I can order. Thank you.

Your balance looks similar to our plain channel Series 770, but with a 15-014 knife lock shoe attached at the end of the cord. We can custom make this configuration for you, if you'd like.

Before we go any further, though, I had a few questions.

First, can you confirm the length of the metal channel and the exact weight of the sash? Can you also tell me how the balance installs at the top of the track (with a screw, hook, or otherwise)? Finally, how many of these did you need?
