27 inch channel balance

Hello there!

Your hardware looks like it could be a match for our S380-27 or S385-27 channel balance. Allow me to go over the difference. The Series 380 comes attached with a 1" deep shoe, while the Series 385 comes attached with a 1-3/32" deep shoe. Measure as shown in the diagram below to determine the best match. You will also need the 2640 strength option, based on your 26 4 stamp.
