Channel balances

Question

Strings broken, so probably not run correctly. Cannot find brand name on window.   Channels have 2040 stamped on them.  Each channel is 21" long.

Thanks for posting. This looks like either an S380-21 or S385-21 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2040.
