These large Rare Earth magnet cylinders are incredibly powerful and should only be handled by people experienced with the power of neodymium magnets. The D2000H is a very strong magnet and must be handled with caution. Due to their 2 inch length, it is not terribly difficult to get a good grip on them in order to pull them apart. But don't let that fool you, the D2000H still packs quite a punch.
