Ergun Aral shows how to measure for a divider rail on inside-mounted shutters. The key: use the same measurement format as you did for the overall shutter unit. For direct mount, hang strip, and Z frames, measure from the window sill up to the center point where you want the divider rail.

In this video, we'll be discussing how to measure for a divider rail or split tilt for an inside mounted shutter. The measuring principle for divider rail is simple. Use the same measure format and measure reference point for measuring divider rail placement as you would for the larger unit itself. And this is regardless of window type. It's the frame type that's important here, since direct mount, hang strip and Z frame all require using a window opening measure format. When measuring for divider rail placement with these frames, measure from the window sill up to the center point where you want the divider rail.
