The screw pin version of shackle is ideal for the joining of two
closed-end items together, such as wire rope assemblies, turnbuckles and
eyebolts. The small hole in its pin offers a back up safety feature by
securing a wire or cable tie through the holes and around the body of
the shackle. This prevents the pin from loosening through vibration and
is known as “mousing” the shackle. Shackles are rated for overhead
suspensions because of this redundant locking feature and the radius
portion of their body structurally accommodates three way bridles.
