Broken Channel 3230 Parts

A contractor from Annapolis, MD says:
I have a customer with a window that has a broken channel set. It is stamped 3230 but the plastic parts are completely missing or broken. The bottom pc is 15/16" from front to back, and side to side (tabs). The top pcs look broken and are 1-1/8"-1-3/32" wide at the tabs. Can you please tell me what you think I need.

Thanks

Thanks for posting! Before I can offer an applicable replacement for this channel balance, I just need to know a bit more information about the bottom attachment. You say that it is 15/16" from front to back, but I do not think that is the same depth that is noted as the major difference between our 15-004 and 15-005.

Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

I believe that your top attachment could be our 19-031, but broken. I can't be sure though. Does that look right to you?
A quick learner from Annapolis, MD says:
I think that the 15-004 and 19-031 are correct, but I cannot find a balance with those parts installed. Can you please price 2 channel balances for a replacement that is stamped 3230. I will need them by Thursday if possible.

Are you sure you may not have our 15-005? Our Series 371 uses a 15-005 and 19-031.

If you are positive that you have a 15-004, however, take a look at this Custom Channel Balance Order Form that I have started for you and fill out the rest of the information. One of our representatives will get in touch with you shortly thereafter.
