Manually operated, these models raise or lower the worksurface approximately one inch per five crank revolutions. The hand crank adjustable height upgrade must be purchased at the same time as the workstation and is available for both Single and Double Side workstations (each unit adjusts a single worksurface – two units are required to control both worksurfaces on Double Side workstations). Please review the Ordering Tips for this product.

On Double Side mechanisms, a support panel is added between and at the bottom of the uprights as a workstation stabilizer and to assist with the assembly of the units. Please review the the Ordering Tips for this product.
