The Magnetic 25-50-75 Blocks are the larger, beefed up version our magnetic shop shims. The blocks have 2 powerful rare earth magnets flush mounted on each of 3 different faces while their opposite faces remain without magnets.
You will find yourself reaching for these all the time instead of digging through the scrap bin.
If you weld everyday, don’t even bother finding a place to store them, just attach them to the side of your table or table legs.
Ground parallel and square on all 6 sides.
