A spreader bar is a physical restraint used in
bondage play. It is a stiff bar typically two to three
feet (sixty to ninety
cm) long, though some can to varying lengths, with attachment points for
restraints at each end. They may include extra attachment points along their length for collars,
suspension play, or as anchoring points for ropes or chains. Not all spreader bars, however, are designed to support the weight of a person.
