Tetragon carriers the top selling handcuff in the world from Peerless!

Peerless Handcuff Company was established in 1914 in Springfield, Massachusetts. Now,100 years later the classic swing through design of the original Peerless® handcuff continues to be an industry standard.

James Milton Gill founded the company after purchasing the patent for a new handcuff design that would revolutionize the law enforcement profession. The inventor was George Carney. Carney’s innovation was the now familiar swing through self locking handcuff. Unlike other restraints of the day, this design was relatively lightweight and easy to carry. The new style handcuff also gave officers a significant advantage since it was easily applied and effectively restrained both hands. The combination of lightweight and ease of use greatly increased officer and public safety.


The new Peerless handcuff quickly became popular, rendering other types of handcuffs obsolete. Over time, and after the patent expired, the design was copied by most other handcuff manufacturers.

Now in its fourth generation, Peerless Handcuff Company remains a family business committed to producing the finest restraints available. We offer a full range of metallic restraint products and accessories. These products are used by law enforcement, correction and military agencies throughout the Canada and abroad.

Your trusted source for police equipment in Canada since 1985.
