I purchased these to use on my 1" dumbell bars that have a threaded lock system. They are so close to being perfect, but if you use the dumbell in a vertical position (goblet squat or overhead tricep extension) the lock will slip in position, and this is only with 2 - 5lb plates pushing against it. I wouldn't even try it with more than that will fear of the plates crashing down.Other than that, they are quick and easy to use. Seem relatively durable and work great when the bar is in a horizontal position.
