A pack of four height-adjustable feet for levelling benches, machines, etc. Fix the brackets to the bottom of each leg or corner of the bench and then adjust the height with a hexagon key in the recess in the top of the screw. If used inside a cabinet, a hole will need to be drilled through the bottom shelf to give access for the hex key. The length of the foot is 75mm and the height of the bracket is 60mm. Load capacity is 270kg per leveller. A superb way to prevent your pencil always rolling off the bench.
