can you tell me which channel balance I have?

A home owner from Tigard, Oregon says:
See images for the end pieces, but the length is 22 inches and it's 1/2 an inch wide. Not sure which model. Help? Thank you so much!

Thanks for posting. Sounds like you have a 22" block & tackle balance with a stamp option of 2120. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.

I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.

It's not a block and tackle balance, it's a channel balance 1/2 inch wide. I thought I was uploading multiple images, but it looks like only the last image is showing. So now I've uploaded more. Because the photos of your channel balances show the top and shoe pieces disconnected from the metal channel, I cannot tell which model of two possibilities it is. Could be 351 or 390, which look the same to me in the photos.
Thanks.

Thanks! Take a look at our S390-22. I think this should work for you, but the only way to confirm is to measure the size of your bottom shoe and compare it with the two Series you picked out.

Also, a "Block & Tackle Balance" is another, more descriptive term for a balance with a pulley and cord system.
