Shackles
& Clevises

Description

Shackles and clevises are U-shaped mechanical couplers shut by a pin or bolt. They attach a chain, cable rope or synthetic sling for rigging, towing and lifting. They’re constructed with several shapes, pin styles and strengths. The size is specified by the diameter of the body, not the size of the pin. Shackles are primarily used in construction, rigging and lifting. A clevis is utilized in less demanding applications such as farming and towing.

Types

Anchor Shackles

Anchor shackles (a.k.a. bow shackles) are better suited to more than one connection due to their larger loop.

There are generally three types of pins: screw type, pin type, or nut and bolt.

Chain Shackles

Chain shackles (a.k.a. D-Shackles) are meant for lighter duty applications. Load in-line only as side loading can bend or twist the shackle (see image).

There are generally three types of pins: screw type, pin type, or nut and bolt.

Utility Clevises

Utility clevises (a.k.a. farm clevises) are narrower than anchor shackles. They are great for connecting smaller equipment. The twisted clevis is great for more awkward connections. DO NOT use for overhead applications.

There are generally three types of pins: screw type, pin type, or nut and bolt.
