Thanks for posting. I'm afraid I can't determine what you have based on this information alone. 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.

Hi, sorry I missed your email question....I have determined the balance rods (2 different windows)are both 29" series 380 Channel Balances...one set is stamped 28 2 BV CMC 7 and the other is stamped 28 C 30...can you please tell me what weight option to choose for each

Sure! A stamp of 28 2 usually corresponds to our 2820, while a stamp of 28 C usually corresponds to our 2830. You can also weigh your sashes to confirm, we should have a chart on each balance store page that shows how much weight each stamp can support.
