Hey, looks like I am going to need six of these balances replaced. These are for single sash Blomberg windows. Do you have some thing that might work for me? The white plastic piece at the end with with the shock cord is about 29mm wide. Overall length is 23". Metal part length is 22".

Thanks for writing in! I am confident we can supply you with replacement balances however, I'll just need a bit more information. To start, I'll need to see a photo of the bottom attachment of the balance. The top and bottom attachments are what help us to determine the series balance you'll need.

The stamp indicates the weight range your balances should be able to carry to support the weight of the sash.

Please let me know if you have any questions.

Yes, these photos are very helpful! It looks like you have either the S351-22 with a 1" shoe or the S390-22 with a 1-1/8" shoe. To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. 

You'll need to select the 2130 option.
