I would like to know what replacement part is needed that matches this window channel balance. The only markings are the "27 4 DN CALDWELL".
The metal section from the plastic end to the other seems to be 27in long.

Hi there!
With this combination of attachments, you could have either an S380 or S385 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 a spring strength option of 2740.
When measuring your balance, be sure to only measure the metal channel. Your stamp is 2740 which indicates a metal channel length of 28".
If you have any further questions just let us know.
