Screw pin anchor shackles (also known as a screw pin bow shackle) are designed to offer the
security of a strong connection with the ease of a quick release pin. The bow shape has the ability
to handle a wider variety of connections and multi-dimensional pulling, as opposed to chain shackles
(also called D shackles) which have a more narrow profile and are meant to be used for straight line pulls.
