The AmStaff Fitness Crumb Rubber Bumper Plates have the perfect durometer rating to absorb bounce and shock, preventing damage to your Olympic lifting bar. Crumb Rubber Bumper Plates are built from a nearly indestructible marriage of recycled vulcanized rubber and a 2" stainless steel insert, giving you 10,000 - 30,000 drops and reducing stress on the lifting bars. The field tests have shown that AmStaff Fitness Crumb Rubber Bumpers bounce less than other high-end rubber bumper plates on the market, which means that they absorb more shock and make less noise.

Proper Use: 10lb and 15lb plates are not meant to be dropped on their own. These sizes can be dropped only when combined with heavier weights (25lb, 35lb, 45lb & 55lb). If dropped on their own, plates may crack/break. Improper use will void the warranty.

Warranty: The 10lbs and 15lbs AmStaff Fitness Crumb Rubber Bumpers are covered under Fitness Avenue’s 6-month warranty from the time of purchase. The 25 - 55 lbs rubber bumper plates are covered for 3 years from the time of purchase.
