See the photo below? Measure your bottom balance attachment just like that. If your metal bar measures 27", then you can use the measurement of the attachment to distinguish between the very similar S380-27 and S385-27. For a 1" shoe, choose Series 380, and for a 1-3/32" shoe, choose Series 385. Then, weigh your window sash and compare to the chart on our site to get a weight "option." Yours may be "2650" based on your "26 5" stamp.
