50mm 2'' Office Chair Caster Set of 5This listing is for one 5 piece of our 50mm or 2'' diameter Twin Wheel Chair Casters. These casters are made to replace chair casters but can also be used on Dinette Chairs, Office Chairs, Home and Office Equipment, Furniture, and Store Display Stand Fixtures. The Nylon Twin Wheels are easy to roll and non-marking, great for all floor types including wood, vinyl, tile, carpet, cement, and more. The load capacity per Chair Caster is 90 lbs each meaning that a complete set of 5 Chair casters can support weight up to 450 lbs if your chair is able to support that much weight. You will need to check your chair's manual or specifications to see if the chair is capable of handling this much weight. Use the capacity of the chair or casters depending on which item can handle less weight to be safe. Grip Ring stem casters are extremely easy to remove and install on your chairs. Simply remove the old chair casters by pulling, popping, or prying the old ones out. Usually, a good pull and the casters should pop out. To install, simply press the grip ring stem directly into the hole until the casters sit flush on the base of the casters raceway or bottom of the stem.If you need to order different quantities or singles please Click Here to visit the single listing page of this same product.Order On Amazon
