Patent pending SDS 'Secure Dumbbell System' combines one-piece cast heads with steel inserts, pinned, press fitted, and welded. Their compact design makes them shorter in length and easier to handle than conventional dumbbells. Durable rubber coating prevents damage to floors and equipment.
SDRS550 set includes (2 each) 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50 lb. Hex Dumbbells.
