Lawson window channel identification needed

Question

My windows are about 9 years-old and the channel balance moving parts are beginning to fail.  I need to replace at least 2 but will buy more.  The channel is 30 inches long (metal only).  I have attached some photos including the markings.

Hello! Thanks for reaching out to us. We can supply this balance, but it has to be a custom order due to that stamp. What that tells me is that this is a heavy-duty strength option that none of our standard options can replace.

What I'll do now is email you a purchase link and price quote that will let you add 2 custom balances to your cart. These will be made to the same specifications as your original.

Please let me know if I can answer any other questions or be of further assistance!
