An immovable rod had a button on one end that could activate and deactivate the magical effect of the rod. Once activated, an immovable rod was magically fixed in place, even if it was located in midair. The rod could hold up to 8,000 pounds (3,629 kilograms) of weight or withstand an equivalent amount of force.
