I am looking to replace a window balance for a non tilt window. My home was built in year 2002. The windows are original. The metal part of the balance is 28 inches long (without the plastic parts protruding). The stamped marking on the photo reads, "27 4 BSI nj." Thank you, Dave

Thanks for reaching out to us, Dave! Your balance's configuration is a match for our S380-28 or S385-28 but the best match will depend on the size of the bottom shoe. Our Series 380 has a 1" deep shoe and the Series 385 has a 1-3/32" deep shoe so you'll need to measure as shown below. You will also need to select the 2740 spring strength option based off your 27 4 stamp.
Let me know if you have any questions and I'd be happy to help!
