Progress through three heights with this steel plyo box set featuring 12, 18, and 24 inch platforms rated at 500 lbs each. Powder-coated welded steel tubing in a trapezoidal frame prevents tipping during explosive plyometric workouts. Textured silicone top pads provide reliable grip, and non-slip rubber feet anchor each unit to the floor. All three boxes stack inside one another for compact storage when your agility training or Hiit session ends.
