The SHN handcuffs combine clever design, advanced materials and modern manufacturing technologies into a highly functional and reliable security product. The body of the handcuff is made of a lightweight magnesium alloy, the same material used in advanced automotive components. By using an injection molding method, the shape of the body can be made very complex, allowing multiple functions to be integrated into a single component: handcuff, housing and connector. The alloy housing is coated with a durable non-stick coating, which provides reliable and proven protection against corrosion and therefore allows for easy cleaning of the handcuffs. The standard color of the coating is matte (flat) black, which reduces visibility in low-profile applications, but a variety of colors can be selected.
