Erik Schouten, Invented the RockSteady Clip after a friend was injured in a drywall accident. A typical drywall stack on a construction site weighs more than 2,000 pounds, if allowed to become unstable it can fall, causing serious injury and even death.The RockSteady Clip prevents vertically stacked drywall from falling over and injuring a worker or jobsite visitor. Allowing the drywall to be stacked vertically keeps both drywall delivery person and installer from placing or lifting heavy material from floor level. This action is considered high risk for acute and cumulative lower back injuries.
