Vulcan Bumper Plates are engineered to withstand the demands of Olympic weightlifting and CrossFit® workouts. Our plates are constructed from a harder, denser rubber compound, allowing for a thinner profile that enables more plates to fit on the bar.

Key Features:

• Durability: Unlike lower-priced brands, our plates are designed to be dropped without the risk of "waffling." Many competitors offer minimal or no warranty and state their plates are not meant for dropping. Vulcan Bumper Plates are made to be dropped!

• Insert Technology: Our forged solid steel inserts are anchored into the plate, ensuring longevity. We introduced this technology in 2011 and have replaced very few plates out of thousands sold.

• Performance: Experience a snug fit on the bar with a dead blow/low bounce effect when dropped, significantly reducing noise compared to lesser brands.
