Based on your 15-5 stamp, I know you have a 16" channel balance with a 1550 stamp option. To place a full order, you'll also need to know the Series. These balance attachments tell me you need Series 380 or Series 385, but you need to measure as depicted below. If you come up with 1-3/32" like in the photo, you have S385-16. If it's 1", it is the S380-16.
