Jumbo Miracle Chair Caster, 100 mm, hard

These Jumbo Miracle Casters are nearly 4 inches in diameter, twice the diameter of the cheap casters on most office chairs. Because of their large size, 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.

Price is for one (1) caster. Order a quantity of five (5) casters for a typical 5-star chair base.

Specifications

• Caster body is made of high impact modified polyamide 6.
• Extra-large 100 mm (3.94") wheel-diameter rolls easily on soft flooring.

  Note: Installed height is 4-7/8". In most cases, this will raise the height of your chair.

• Strong 220 lb. load capacity per caster, which means that a set of five supports a static load of 1100 pounds. However, for best results, we do not recommend Jumbo Miracle Casters for individuals over 500 pounds.
• Hard tread is designed to roll easily on carpeted and padded floors. The tread is non-marking and non-abrasive, however we do not recommend them for use on hardwood or tile floors.
• Universal 11 mm (1/3") diameter x 19 mm (3/4") long mounting stem. Fits most, but not all, office chairs
