Hello! Looks like you have an old Security window. We should be able to make this balance for you, though it will need to be a custom order. I'm thinking of our 15-005 and 19-042 as the two nylon attachments. Look them over and tell me if you agree. Before we begin on the rest, can you tell me what stamp is printed on the metal channel? If you don't have one, or if you aren't sure, we will need the weight of the sash, instead. I will also need to know how many you're interested in.

Thank you for the update! I highly recommend getting the exact weight of the sash. Since we have to custom make this, it's important that the spring strength is calibrated correctly. These are precise systems and having the wrong spring strength can cause problems. We like to nip that in the bud and ensure that we get you only the exact hardware you need. See the video below for help on how you can remove your sash.

Great! We'll go with a 2320 option, which can carry 9 through 15 pounds. I'll send you a link for two of these, along with a price quote. If you'd like to adjust the quantity, let me know!
