5-pack of black plastic office chair caster cups

Five black plastic 2-inch office chair caster cups are specifically designed to secure wheeled office chairs and wheelchairs, preventing accidental slippage and protecting floors from wheel damage. A unique advantage of this product is its thickened design: both the cup walls and base are made of thickened engineering plastic, exceeding 3mm in thickness, ensuring the wheels won’t crack the base even when a heavier person sits on it. The thickened design also increases the contact area with the ground, distributing pressure and preventing deep dents on cork floors or mats. The black cups are stain-resistant and discreet, suitable for most office environments. By placing each chair wheel into the thickened cup, you can comfortably recline and type without worrying about wheel marks or dents on the floor.
