Material and construction Main body is hard aluminum alloy, CNC machined for a precise, smooth, bright surface. Stainless steel support rod provides antirust and anticorrosion performance for long service life. Maximum lift and operation Hand crank lift capability up to 47 mm (1.85 inches) for precise height adjustments and smooth operation of trimming and engraving tasks, improving overall workflow efficiency. Easy installation Includes 4 mounting screws. Simple ontable installation: fix the threaded support rod to the table to secure the lift quickly and reliably. Compatibility and applications Suitable for router lifts on workbenches, woodworking stands, and electric milling stands. Can clamp edge trimmers with a diameter of 63.865 mm (2.512.56 inches). Use scenarios Scenario 1: On a standard workbench, use the lift to adjust bit height precisely during trimming and engraving projects, helping achieve consistent results. Scenario 2: In a small , upgrade a milling stand with the lift to enable rapid height changes for edge trimming and edging tasks. Scenario 3: In a versatile setup where different edge trimmer diameters are encountered, use the clamp range (63.865 mm) to secure tools quickly and safely, reducing setup time between operations.
