CasterHQ specializes in high-quality replacement chair and furniture casters. Our universal-size stock fits the majority of chairs on the market, making it easy to change out your caster and wheel to accommodate your flooring needs. We supply chair casters and wheels for office chairs, furniture, and dinette chairs, and we have a variety of options for chairs and furniture on carpet, tile, and hardwood floors.
If you’re looking for additional floor protection, you can browse our softer gray rubber wheels that are non-marking and work wonders for bamboo, hardwood floors, and some types of short carpet. Shaggier, thicker carpet types may need a harder, non-marking polyurethane wheel or a standard chair caster that includes a dual non-marking polyurethane wheel for an easier time rolling through your day. In addition, most chairs that come with 2” wheels can easily be upgraded to a larger 3” wheel to increase the rollability and ergonomics of the chair.
It’s Very Important To Measure Your Chair Caster Stem Before Ordering
We recommend that you always measure your chair caster stems before placing your order. Please make sure to measure your chair caster stem correctly. Do so by using a 7/16" wrench and see if it fits over the chair caster's stem where it's snug/flush. Using a ruler or tape measure can also work to help find your 7/16" spot. Simply find 7/16” on the tape measure; it should line up about 1/6" under the 1/2" mark. If you have questions, please look below for our phone number or email and one of our caster and wheel experts will be glad to assist you.
Measuring Grip Ring Stem Casters for Chairs and Furniture:
The Stem Diameter should be: 7/16" = 0.4375"
Stem Diameter: 7/16"
Stem Length: 7/8"
To measure your Grip Ring / Friction Ring Stem Diameter use a 7/16" Wrench and it should fit nice and flush against the diameter of the stem. You could also get a 7/16" Drill bit and insert into the hole of the chair or leg and it that fits flush then any of our chair casters will replace your casters with ease.
