Medical Restrainers use an effectively designed, triple securing system - these restraints cannot be removed by a patient who does not have one hand totally free. And, if the freedom of one hand is necessary, they can be locked using a standard pad lock. Lightweight, yet exceptionally strong, Medical Restrainers are made from 2"wide, 1400LB strength polypropylene webbed belting with hook & loop material. They feature a detachable Tri-Lam pads for use on the ankles and wrists to protect patients from self-inflicted injuries.
