My balance doesn't stay with the window

Many thanks for your correspondence. There are a few factors here that could affect the balance's performance in your window. Firstly, what is the 'depth' of your balance's bottom shoe? The 'depth' is the distance between the 'heel' and 'toe' of the shoe. Second, what is the length of your original balance's metal channel, and what stamp code does it have? Similarly, what length and stamp option did you select for the Series 350? Finally, could you tell us the height of the visible glass in the window sash that you are using these balances for? From there, we'll try and identify any further issues. Many thanks.  

Thank you! 1-7/32" is very large. I'm thinking our 15-003 may be what you want, which has a heel-to-toe depth of 1-3/16". It also has a more dramatic "slope" in the shape, similar to your original. Now, that doesn't necessarily mean anything important, but I think it's worth noting in this case.

We can custom make a Series 350 but with the bottom shoe swapped out for our 15-003. Is that something you'd like us to do? If so, I'll need to know how many of each balance you need.

Which brings me to another question: you implied that you have two different sized windows, but when you broke it down you described the same balance twice: 29" long with a 2820 stamp. Was that a typo? 

Once I've confirmed the size, stamp, and quantity of every balance you need, I can email you custom order links and a price quote for each one.

Sure thing! I'm here at your convenience.
