Hi there- thanks for your post!

I was able to narrow what you have down to two options. You either have our Series 351 or our Series 390 channel balance. The difference lies in the depth of the shoe. Our Series 351 has a shoe depth of 1" and our Series 390 has a shoe depth of 1-1/8".

Double check the length of your metal channel to select the correct length at checkout. Lastly, you will select the 3420 option which corresponds with your "3420" stamp on your metal channel.
