Hanging Strap Cage Belting quality leather strap cage with leather upholstered wooden base. Entry is gained through the bottom opening and the cage is suspended from six welded D rings. Once the cage is suspended off the floor the weight of the occupant causes the straps to tighten equally around the body thus immobilising the person inside, like a giant Chinese Finger Trap. A strong metal loop at head height prevents the head being crushed when it is under tension. When the person is hooded it creates a fantastic head trip! The minimum effective height for lifting is 2.7 metres. Always ensure your lifting gear is in good working order and capable of bearing the load before undertaking any form of suspension work.
