How the Magnetic Permanent Block Works:
Easily clamp flat, circular, square, and other sections with the MPI Magnetic Permanent Block MPB. The magnetic block has three specially modified sides each for a different shape of component. It is easily activated using the switching key. The chucks are sold in three different sizes. To expand the clamping area, simply connect the blocks using the hexagon connectors (sold separately). Theese chucks are completely nickel-coated so they are highly resistant to corrosion.
