Hi Mark,
Thank you for your question about Master Caster Duet Twin Wheels.
Unless you have an office chair by Steelcase, a manufacturer that welds the stems to base, your caster stems will come out. It's just going to take some force. Try using a pair pliers, or hammer and flathead screwdriver to pry them out.
If you do have a Steelcase Chair with welded casters stems, you can special order stemless casters. Just give us a call at 866-501-6055. However, if you currently have 7/16" C stems, they can be removed. Plus, the stemless casters won't fit. Stemless casters only fit 3/8" diameter stems up to 1-5/16" long. Use a string to carefully measure your current casters' diameter.
Hope this answers your question!
Best,
Frankye
