Durable aluminum router lift with precision finish - Material and durability: The main body is made of hard aluminum alloy with CNC processing for a smooth, bright surface. A stainless steel support rod provides anti-rust and anti-corrosion performance for long service life. - Smooth, precise lift: Maximum lift is 47 mm (1.85 inches) using a hand crank, enabling smooth height adjustment for trimming and engraving tasks and improving overall efficiency. - Easy installation: Includes 4 mounting screws for quick mounting. Simply fix the threaded support rod to the table. - Broad compatibility: Suitable for workbenches, woodworking stands, and electric milling stands. It can clamp edge trimmers with a diameter of 63.8-65 mm (2.51-2.56 inches). - Key benefits: Robust construction, precise height adjustment, corrosion-resistant components, straightforward installation, and reliable performance in common router and edge-trimming setups. Use scenarios - In a home or small shop, mount on a woodworking workbench to raise and lower a router for precise trimming and engraving passes, improving control and consistency. - On a portable milling or edging stand, quickly adjust height to accommodate different material thicknesses during edge trimming tasks. - In cabinet making or furniture finishing, clamp a 63.8-65 mm edge trimmer for flush trimming and consistent depth control across projects.
