These Jumbo Miracle Casters are nearly 4 inches in diameter, twice the diameter of the conventional chair casters. Because of their large size and hard tread, Jumbo Miracle Casters roll easily over thick carpet, eliminating the need for a chair mat. Imagine the huge wheels on tractors and other heavy equipment. Miracle Casters work on the same principle. The bigger the wheel, the easier it will roll on a soft or uneven surface.
Universal mounting stem11mm (1/3") diameter;19mm (3/4") long.
When used on carpet, each Miracle Caster is guaranteed against failure for 10 years. Miracle Casters fit many office chairs.
