Window Balances
Hey there,
Thanks for reaching out! Your observation is correct. These are not a standard balance, they are an Extended-Travel Channel Balance and will need to be a custom assembly. I am confident that we can supply you with the replacement balances you need. Although, you should be aware that the length of the metal channel for the balances we'll be supplying you with is 19-7/8". So, with that said, if yours are truly 19-1/2", our balances will not work to replace yours.
I've just forwarded over a separate link with a quote for (2) of the requested balances. Please let me know if you need a higher quantity of balances and I'll be happy to update the quote for you.
You'll be able to use this link to review the pricing of these balances and to place them in your online cart to make your purchase. Be sure to check your spam/junk folder for the link if you do not find it in your primary inbox.
Please let me know if you have any questions.
