Help finding correct balances for an old window

We can supply your original balance, but it will have to be a custom order since it's no longer a stock configuration. I actually don't even think these windows are made anymore. 

These are a little tricky, too, since they're asymmetrically designed. What that means is that the left side is a different configuration than the right side. You can actually see what I mean in your photos: one side has a bottom nylon fitting while the other side does not. This is the intended design.

With that in mind I'll need more information from you in order to determine exactly how we need to make these balances for you. First, can you tell me what the stamps printed on each side read? Please differentiate between the side that has a shoe and the side that doesn't have a shoe. Can you also tell me the length of the metal channel in each case? They should be the same. Finally, how many of each did you need? 

Thanks for getting back to us. One of our team members just sent over order links and price quotes for your hinge balances. You'll be given multiple shipping options to choose from at checkout with delivery estimates. 

We also offer the 15-058 hinge assembly used with these balances. Take a look and let us know if you need anything else. Thank you.
