Sankaku Channel/manacles

A restraint device used to lock a persons's wrists or ankles together. The most common design consists of two sturdy metal braces that are locked together by a chain. They're an older version of the modern handcuffs.

Manacles differ from handcuffs with their heavier, shackle-like design and darker color. Manacles sometimes have a longer chain which allows for a greater degree of movement.
