FAQ: "Will these fit on my office chair?"
Answer: Most modern office chairs use a 7/16" diameter stem - they're almost universal. We recommend you check your current caster stems just to be sure. Measure the diameter by setting one stem next to a ruler. If your stems are skinnier than 7/16" diameter, see our other options.
Installation is easy. Your existing casters will pull out with the old stem still in them. Now just push in the stem on your new casters. Its that easy!
