This is a simple design that provides a soft (TPU) cover over the plates on my dumbbells. This design is sized for plates 150mm in diameter and 26.5 mm in thickness.
I find these covers fit well and seem durable. They keep my dumbbells from rolling away when I set them down, and they are much quieter and gentler on my floor.
