Our Big Barrel Spreader Bars are about twice the diameter of our regular spreaders (it's like a spreader bar on steroids approx 1 1/4" diameter, yet no heavier than our regular spreaders), they feature (3) welded loops for attaching rope, chain, leash, etc to and we've attached our high quality black neoprene restraints. These restraints are awesome, both look and feel! You can get these wet you can get lube all over them and they will stand up to the wear and tear. The neoprene on the inside has a padding feel that are great for long bondage sessions. Super strong construction, no worries about these restraints falling apart on you. We also have optional hand made Leather restraints. These are locally made and super high quality with locking buckles. We are also now offering our Big Barrel Spreader Bars with either Neoprene or hand made Leather Restraints (leather cuffs available in Black, Red, Pink or Purple).
