Excellent Magnet
These magnets are amazing. 19Kg of force is finger breaking. I use a couple of this magnets to hold up dust extraction on a bandsaw and they have proven to be more than adequate. They have a lot of surface area and so they apply the magnetic force over a wide area which allows the magnet to hold and not slide when holing up the weight. They only issue I have is not getting your fingers trapped between them when you are moving them from one place to another. I have recently bought a couple more as I know they will perform the best out of all the magnets I have used so far.
