Balance from Millard Window

Hi! I don't know the depth of your bottom attachment, so I can't say for sure. Measure for yourself and you can tell: see the photo below. If you have a 1-3/32" shoe, choose Series 385. If your shoe is 1" or less, choose Series 380. If your metal bar is 27" long (I have a suspicion), you can choose S380-27 or S385-27. "26 4" is "2640" nowadays.
