The NLE PRO has a unique “elbow” feature allows the arm to reach from the innermost to outermost reach without adjustment. The system uses high quality rigid linear bearings for smooth axis motions, while maintaining the strength and rigidity required for a solid, quality feel. The center “running rod” is supported at top and bottom by steel plates braced on aluminum extruded sections. Zero force balancers provide a smooth yet safe means of load balancing on the stand. Single or dual units can be used to offset any heavy tool payload.
