These are plastic. I should have known better. When they are inserted into the tube, the plastic "wings" that stick out to grip the inside of the tube break off. I had a 100% failure rate. Save your money, don't buy these.

I put these into the posts on an existing shelf so I could attach casters. They worked beautifully!
