Door Restraint Set Turn any ordinary door into an erotic bondage playground with this Door Jam Cuff Set. Simply drape 2 acrylic tubes over the top of an open door, slide the other 2 under the bottom of the door, close the door, and your partner is securely restrained. The acrylic tubes hold securely when the door is closed without scuffing or damaging the door, and there's no need for modification or fancy hardware. The velvet wrist and ankle cuffs easily adjust to fit most sizes, while the strong metal clips and O-rings prevent your subject from escaping. Explore new positions and new scenarios you never thought were possible, all while your partner is bound and at your mercy.
