Space-saving dumbbell racks feature rubber saddles to protect and securely cradle each dumbbell. While Eleiko Dumbbell Racks are versatile and able to house most types of dumbbells, this rack is primarily compatible with Eleiko Pro Dumbbells, Eleiko Vulcano Disc Dumbbells, and Eleiko Vulcano Dumbbells. To increase user safety and rack stability we recommend bolting the rack to the floor.
