Rubber Encased Troy Pro-Style Dumbbells are pre-assembled to ensure that they meet the standards required in heavy used commercial applications. All pro-style dumbbells use solid steel bolt design – bigger longer and stronger than the competition. These dumbbells consist of straight handles that feature special deep set knurling for functional performance and top of the line Troy rubber encased plates. The rubber end caps include the Troy name and numbers for easy identification. Includes one pair 20-pound dumbbells. Photo is for reference only.
