Window balance marked 29 3 BSI VK
We can supply this balance, but it will have to be a custom order due to its configuration. What you have here is an "extended travel" balance, named for its unique configuration. Before we go any further, however, I had a few more questions I wanted to run by you.
First, can you show me a clearer picture of the metal clip at the end of the cord? I think I know what you have, but a different angle would allow me to verify.
Can you also confirm the length of the metal channel? Based on your stamp it should be 29-7/8", not 29-3/4".
Lastly, how many of these did you want to order? We will require a precise count.
Thanks! These photos are perfect. I'll go ahead and email you a purchase link and price quote that will let you add 4 of these to your cart. If you wanted to change that quantity, please tell me here and I will be happy to make any alterations you'd like.
I would only recommend that you get a more precise measurement before you finalize your order. Please also note that this configuration is not currently in stock, so there will be an expected lead time of 5-6 business weeks.
