Dualhandle is a term used across several domains to describe a mechanism or control surface that presents two handles for interaction or manipulation.

The concept appears in human–machine interfaces, tools with leverage, and adjustable fixtures.
In user interface design, dual-handle sliders enable users to set a range by dragging two markers along
In mechanical design, dual-handle devices are used to improve control and leverage. Examples include hand tools
In software and data visualization, dual-handle controls appear as reusable widgets for range selection, constraint setting,
