These retro-tech collars hang on so tight that they bite into the bar. Best applied with a wrench to your plate-loaded dumbbells (but not your fancy new Eleiko bar): the teeth you save might be your own.
Electroless nickel plated. Large size for Olympic bars (approx. 1.97" diameter), 1-1/2" in width. Comes with an IronMind wrench (also made in the USA, of course).
- Large 1 pair (3 lb.) $59.95
- Large 2 pairs (6 lb.) $116.90
