Heavy Duty Leg Leveler with Wide Foot - Adjustable Furniture Leveling Feet for Tables, Chairs, and Cabinets - Perfect for Uneven Floors and Home Office Setup

These levelers are made in Germany and are very solid. They are wide, 1 7/8" between bolt hole centers, so they will not work on narrow legs. I used mine for a table saw out feed table with L shaped legs made from plywood. The threaded post is beefy measuring 7/16" in diameter and the height adjustment is very slick and precise using a 5mm allen wrench in the top of the post which goes through a threaded hole in the base of the leveler. I suggest using at least a #10 wood screw to secure the leveler.
