A 'single lock' model has a total of 4 buttons ( one on each side of the cuff times two cuffs per pair). The term 'double lock' refers to the ability of the cuff to be used to quickly train in the use of the double lock feature found on modern handcuffs. The double lock model features a button to double lock and unlock the cuff quickly. This is in addition to the single lock buttons for releasing the cuffs.
