We need some new balancer parts. I believe these are called "Block and Tackle". They measure 29" longt(he metal portion) and are 1/2" in width. Can you please let me know if you carry a replacement part? We need 10 of these.

Hello,
With this combination of attachments, you could have either an S380-29 or S385-29 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need 2820 spring strength options for your replacement balances.
Thank you and let us know if you have any other questions or concerns.

Sure, the 28B stamp shown in your photo correlates to a 2820 strength option shown on the S380-29 product page, which means that the balance spring will support a window sash between 12 and 16 lbs.
