All Electric Scroller Directories feature cylinders that are 8" in diameter and 44" tall. These cylinders are driven by 115 volt A.C. gear motors controlled by electric eyes. When activated by passing a hand in front of the electric eye, the cylinders advance a short distance then stop, giving you access to additional information during your search. The process can be repeated as many times as needed. Electric Scroller Directory units can have from 4 up to 16 scrollers.
Windy Prairie offers different models of Mechanical (manual) Scroller Directories with Rotating Cylinders Displays. These Displays work well for medium to large cemeteries without access to electricity. The Mechanical Scrollers feature from 2 to 8 rotating 8" diameter cylinders that are 33" tall. Each cylinder is controlled and driven by an external hand knob. These knobs are below each cylinder and are easily turned by hand to access the information stored on the cylinders.
