Keep your sub well-restrained with this 4-point adjustable spreader bar. Available in powder-coated black or polished chrome, this piece will look good with any dungeon’s aesthetic. Your sub can struggle all they want against the adjustable pins: they’re held in place with wing-nuts to prevent escape.
The bar adjusts from 25 inches fully closed to 40 inches opened, and has adjustment holes every couple inches. Get creative with restraint positions by using all 4 hard points and the adjustable length to their fullest potential -- lock up their wrists and ankles, attach the inner points to a collar and the outer points to their wrists for a DIY yoke, or even attach one outer point to a collar the other outer point to ankles and the inner points to the wrists to keep them immobilized and curled up depending on how generous the bar length is.
