The Model 1010 is a stainless steel chain style handcuff with "Trueswing Technology", which assures that the shackle will always swing straight into the body plates and lock itself to the multiple drop bars. Other features include special Positive Click Bak® for fast application and raised rivets for added strength. With a minimal weight a little over 9 ounces, the Model 1010 is made in USA and includes a factory direct lifetime limited warranty.
