The Grip restraints are now available in MRI-safe versions. The standard buckles are made of stainless steel. The MRI safe versions use brass locking buckles and have eliminated all magnetic properties.
Standard metal handcuffs and restraints cannot be used when MRI tests are required on a prisoner. Generally, the transportation officer must un-restrain the prisoner when in the MRI machinery. This creates obvious safety concern for the officer, hospital staff, and general public. The new Grip MRI-safe restraints are the first safe and high security solution.
