I have tried the metal barbell spring clips and another type of clamps. My bar is 1” with a thin urethane coating. The other devices were 24-25mm for a 1” bar. They would not fit. The set of Greententljs 1 Inch Barbell Clamps I purchased are about 1mm larger when fully open. These will slide on my bar and hold the plates secure. I did not rate as a 5 since I have only had them for about a week.
