You are looking at the largest, most powerful, most dangerous magnet we carry. At over 1200lbs of pull force, it is likely the strongest magnet available anywhere! These HUGE blocks are no joke. They are extremely powerful and very dangerous, and as such must be handled with extreme caution.

They will pinch hard enough to break the skin and could even crush if you get between two of them or one and a piece of metal. Much worse than getting a hand slammed in a car door. They are heavy, sturdy, and unbelievably strong. Once a block this large is attached to a metal surface it will be impossible to remove it.

This magnet is not a toy and should only be handled by professionals. We recommend always having at least one other person help you handle this massive block. We use a team of at least three.

You must read and understand our Neodymium Magnet Safety Page before ordering these magnets. You must also agree to our Terms and Conditions prior to purchasing. THESE ARE VERY DANGEROUS!

Due to the special manner in which this magnet must be shipped and the danger in returning it to us, we will NOT accept returns on this item. Please be sure you know what you are getting into before ordering.
