Lock up your prisoner with this great device. This locking spreader bar will lock into place your partners ankles ends of the bar and their wrists to the middle of the bar. While locked in, explore your partners body and put them in any position from spread eagle to doggy style. Once put in, your partner will have no escape and very little ability to move fluently if at all. Since this is a Locking Spreader Bar, locks will be needed to hold wrist and ankles in place. Measurements: Wrist Cuffs: 30.5 cm in length and 5.1 cm in width. Ankle Cuffs: 32.4 cm in length and 5.1 cm in width. Spreader Bar: Spreading width can be adjusted from 43.2 cm all the way up to 65.4 cm. Note: Locks Sold Separately.
