You're in luck. We can do this without photos. The Series 350 is a balance with no wings on top, but wings on bottom. If your metal channel is 33" long and you need that configuration of wings, then choose S350-33. To finish placing your order, the site will require you to select an "option." The S350-33 webpage shows a chart that will tell you which option to choose; you just have to weigh your sash. The reason for this is that the balance needs to lift up the proper amount of weight to steady the window. Weigh up, choose an option, and place your order online! I'm here if you need anything else. |
