Material: Ballistic Rubber
The Sorinex Original Flop will handle the brunt of your drops, kicks, bounces, and stomps. Tile a few together for a workable area to drop weights on and save your floor. The Flop is made from high-grade ballistic rubber that our military uses to stop bullets behind shooting ranges. Use these rugged rubber spacers as an adjustable pulling block or as a 1.5″ height adjustment for box squats or anything else you can think of.
