Chubb Detainer 1K70 Handcuffs

The Chubb Detainer 1K70 handcuffs are a notable example of British restraint technology, combining historical design elements with practical functionality.

🛠️ Design & Features

The 1K70 model is a lightweight, easy-to-apply handcuff designed primarily for arrest purposes. It features a robust construction with dual ratchets and a single groove on the bow, enhancing security. The cuffs are made from LM24 aluminum pressure die castings, with mild steel chrome-plated ratchet arms and nickel-plated chain links, swivels, and pins. The key is a 3-lever solid post, and double locking can be achieved either by turning the key clockwise a full revolution or by pressing the double-locking actuating knob at the base of the cuff. Unlocking is accomplished by turning the key counter-clockwise, with double unlocking requiring one and a half turns counter-clockwise. The cuffs weigh approximately 350 grams (12.3 oz) and are finished with a glass bead blasted body and clear lacquer .rageuniversity.comblacksteel.com+1

🏛️ Historical Context

The Chubb Detainer line has its roots in the early 19th century. In 1818, Jeremiah Chubb patented his “Detainer” lock in response to a burglary at his own home. This innovation led to the establishment of Chubb Locks, a company that became synonymous with high-security locking mechanisms. The 1K70 model represents a modern iteration of this legacy, designed for contemporary law enforcement and security needs .Dokumen

Notably, a variant with a single large connecting ring was included in airline security kits for managing disruptive passengers. These kits, produced by SecuriCare International, were designed for use in aircraft and confined spaces, showcasing the versatility of the 1K70 model in various security contexts .
