Knee Joint For Rescue Randy 9000Randy 9000's joints have been improved to withstand high stress and to protect rescuers’ fingers. The manikin is produced from rugged polyethylene (PE), the same material out of which backboards are made. Randy 9000 comes in individual parts.
Each sealed piece is assembled with stainless steel hardware and is easy to replace. The range of motion mimics real life.
The Knee Joint is a ball joint. Inside the ball valve joints is a ball joint stop to limit the range of motion, making three plastic parts to each joint and the associated nut/bolt/washer combination.
