The Fetish Collection Expander Spreader Bar and Cuffs Set can be mounted on your ceiling using the D-ring on top of the bar. An adjusted bar length of 70 cm to 90 cm and cuffs that are also easily adjusted for comfort! can be mounted on your ceiling using the D-ring on top of the bar. Cuffs are attached to the bar with clip fasteners, so you can detach them and use the cuffs separately. You can also use the ring on both ends to attach other bondage toys, such as ankle cuffs, to the spreader bar.
