Industrial Magnetics Inc.’s MBX magnetic clamping blocks hold steel workpieces in place. The blocks have two opposing magnetic sides, which can be turned on and off, that are designed to hold workpieces to steel surfaces, such as machinery or worktables. They work in horizontal or vertical orientation and can accommodate flat, round, square or custom profiles. The blocks allow access to five sides of the workpiece at once. Blocks may also be connected using a hex rod to accommodate longer workpieces. Three sizes are available with holding values from 1125 lbs. to 2250 lbs.
