CALIPER BUCKLE– it’s the special very efficient system of closure. The system consist of elastic ladder strap and metal caliper buckle with a clever ratcheting system. This system is very easy to use and there is enough to raise the cocking lever. The caliper buckle system is used for producing the orthopedic devices, required precise and strong compression. This system of closure is equipped with release lever that turns the compression immediately off. This fast ‘compression-release’ function is very useful in case of too strong compression, resulting in breathing problems of patient.
