How are chained handcuffs typically described?

Chained handcuffs are typically described as traditional or standard varieties because they consist of two cuffs linked by a chain. This design has been widely used in law enforcement for many years and is recognizable as the conventional handcuff model. Traditional handcuffs allow for a certain amount of movement between the cuffs while still maintaining restraint. The term "traditional" indicates their longstanding use and familiar design in law enforcement and security settings.

Other options relate to different characteristics or types of handcuffs that aren’t specifically associated with the chained design, thereby emphasizing the relevance of the correct answer in the context of typical descriptions of restraint devices in law enforcement.
