These Gear Stock Leg Irons are professional-grade leg restraints. The extra-large cuffs and 18" welded chain are purpose built to confine the subject's legs, while providing just enough mobility to walk. Constructed from durable stainless steel with heat treated internal lockworks. With a ratcheting double lock system, these cuffs are easy to open, but nearly impossible to get out of. An ideal accessory for police, law enforcement, and home security. The package includes two keys for the univeral lock.
