Security Guard Handcuffs are only used by an officer if there is an intruder that needs to be contained until the police officials arrive. They are available in a variety of models, shapes, sizes and brands. Some security companies will provide the handcuffs and other gear you might need on the job, except for the gun, but you are generally best to purchase your own.
Depending on the choice, you can get handcuffs with a chain link, rigid, aluminum, hinged, or chained at the waist. They are usually made from steel, chrome, or nickel.
