Clover ClampsAn excellent addition to your rope play, our clover clamps come with 35 cm chain and just the right amount of ouch. Clover clamps, sometimes also called butterfly clamps (or even Japanese clamps due to their popularity in imagery) are a playful addition to your rope set. The clever mechanism means the grip tightens when the chain is pulled. The rubber tips add grip and a little bit of cushioning.
