18 3 AW CMC 4 Window track balance Identification

Hello again! This one is a lot easier to identify than the last balance you showed us. This will be either our S385-19 or S380-19. As before, you'll have to measure the depth of your shoe to confirm the better match. The S385-19 comes with a 15-004 shoe, which is 1-3/32" deep, while the S380-19 comes with the 1" deep 15-005 shoe.
