- Material and durability: main body made from hard aluminium alloy with CNC precision machining for a smooth, bright surface; stainless steel support rod provides rust and corrosion resistance for a long service life. - Wide compatibility and clamping range: suitable for workbenches, inverted woodworking machines, inverted electric wood routers, and other setups; can clamp trimming machines with a diameter of 64 to 66 mm. - High lifting distance and precise control: general lifting bases may lift up to 40 mm, but this unit can lift up to 51 mm (2 inches); offers about 1 mm lift per turn for fine height adjustment. - Easy installation: includes 4 mounting screws; simply attach the threaded support rod to the table for quick setup. - Practical use scenarios: - On a workbench, clamp a trimming machine to achieve stable height and precise cutting depth during detailed trimming tasks. - Invert a wood router setup for upside-down routing, using the lifting capability to match material thickness and ensure consistent results. - Mount on a table for inverted woodworking operations, adjusting height to accommodate different project requirements and prevent tool clearance issues.
