For the uninitiated, a spreader bar is attached to ankle cuffs to keep a sub's legs, well, spread, during dungeon play and comes in varying lengths. This one is 18", sturdy but relatively light with metal buckles on both ends and covered with studded black leather. A fetish-scene-specific piece of equipment, it is more suitable for stocking in BDSM boutiques and gay outlets, than your neighborhood adult retailer.
