Hello, I need to replace this part for 4 windows. the balance is stamped 27-4. Thanks so much!

Thanks for reaching out! This window balance reminds me of the S395-28. This is assembled with a winged top guide and wingless bottom shoe.

Our 2740 stamp will support a sash weighing between 19 to 26lbs.
