I'm afraid I cannot determine what you have based on the stamp 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. I also recommend weighing your sash on a scale to determine the strength of the spring. Yours sounds like it's for a particularly heavy sash, which means it may need to be custom made. Let me know.

Hello! Yes, the stamp indicates how much weight two balances working together can carry. It's a good idea to weigh your sash just in case. Your stamp indicates that it might be 50 pounds, but since these would likely have to be custom made I would like to confirm just in case.
As for lubrication, try silicone spray instead. I find that oil tends to attract a lot of dirt and debris, which can just make matters worse. |

Great, thank you! I'll send you a quote for two of these immediately! You can also use the link I'm about to email you to add the special balance to your cart.
