I'd like to replace this channel balance. The length of the metal rod (excluding the plastic pieces) is 28 inches. What part should I buy?

Thanks for reaching out! I am confident you'll need the S385-28 Channel Balance will work to replace the one you have here. Although, you'll need to double check that your shoe depth is 1-3/32". Take a look at the diagram below for reference.
Since your balance is stamped with a 27 4, the 2740 should work fine for your repairs but it may be able good idea to confirm that you sash weight falls between 19 to 26lbs.

Comparison of the S378, S380 and S385 balance shoes.
