Channel balance window

Question

I would like to replace the window channel balances. The existing one is stamped 26DS BS1 of 37. I am looking at Series S385-27. Which option (stamp option) best suits my existing one. Regards

Hello from SWISCO.com. For your Series 385-27, the spring weight for 26DS 37 would be our 2670 for a sash weighing between 36-39 pounds.
