Always be ready for resistance, even if the suspect seems to be cooperative. If you are within six feet of a suspect you need to act as if you are anticipating a struggle. Speak confidently, keep your grip on firm, and apply the handcuffs swiftly. [2] X Research source
Try to avoid handcuffing a person directly against an object like a wall or car. If they decide to resist, it will give them a surface to leverage against and they may injure themselves or you.
While keeping your balance, try to limit theirs. Have the suspect spread their feet apart and bend slightly forward, or handcuff them while they’re kneeling on the ground.
Be knowledgeable about your handcuffs. Always read the manual in advance so that you will know the information you need to know. There are several kinds of handcuffs so you need to be familiar with your own.
The chain of the handcuff should be coming out of the back part of the hand and further from the body. In this position, the suspect can’t move their hands under their legs and in front of their bodies. [3] X Research source
A double-locking mechanism is a lock that ensures the cuffs can’t get tighter once they’re placed on the suspect, reducing the risk of injury. [5] X Research source
Some people find it helpful to hold the suspect’s thumbs together to help restrain them.
Always double check the tightness of the handcuffs. You should be able to slide your smallest finger between the cuffs and the person’s wrist. Leaving the cuffs too tight can result in nerve damage to the suspect. [6] X Research source
