Because of the rigid bar in this type of handcuffs, these tend to occupy more space on a belt whereas the chain link could be folded; the rigid type decreases the number of possible wearing positions. Typically, the cuffs are worn in a specially designed holster at a 45° angle, on either the left or right side of the officer, depending on whether they are left- or right-handed. These types of handcuffs are known as "speedcuffs" or "quickcuffs", as the rigid bar design allows the officer to easily control the suspect and a much quicker placement on the wrist of the offender. Rigid handcuffs are most popular in the UK.
