Binding or other devices that change the shape of the kneeling roll from a cylinder are:

• A. Permitted with supervisor approval
• B. Allowed for certain divisions
• C. Not permitted
• D. Required for stability

Answer: (C)

Equipment rules keep certain parts of gear standardized so everyone competes on a level and safe playing field. The kneeling roll is designed to be a consistent, cylindrical shape; when you bind it or add devices that change its shape, you’re altering how it contacts the floor, how weight is distributed, and how stable the participant is during use. Those changes can create uneven performance conditions or new safety risks, which is why such alterations aren’t allowed. Allowing modifications—even with a supervisor’s OK or only for some divisions—would undermine safety and fairness, so the rule states that these modifications are not permitted.
