Anchor, Bow, Chain, and D Shackles

Shackles are a versatile tool for connecting lifting slings, wire rope, chain, and rope - these connecting links are essential for a variety of rigging, lifting, pulling, and hoisting applications.

Because they come in a wide variety of styles and types, with so many different options available, choosing the right shackle for the job can be confusing.

We've outlined some of the basics below. If you have any questions, contact one of our product specialists on our sales team.

Anchor/Bow vs. Chain/D-Shackle

The terms anchor shackle and bow shackle are usually used interchangeably, as both names refer to a shackle with a larger, rounded "O" shape look. However, a bow shackle typically has a larger, more defined "bow" area than an anchor shackle. Their rounded design allows them to take loads from many directions without developing significant side load. The larger loop shape does reduce its overall strength, but it's also able to handle a larger strap.

Chain shackles are also known as D-shackles, referring to the "D" shape design. It's narrower than a bow or anchor shackle and generally has a threaded pin or pin close. The smaller loop is designed to take high loads primarily in line, as side and racking loads may cause it to twist or bend.

Galvanized vs. Stainless Steel

Galvanized metal and stainless steel both offer excellent protection from rust and corrosion, making either a great choice.

In general, galvanized shackles are ideal for industrial applications where moisture is not a major issue. Galvanized steel has a coating of zinc oxide to protect the steel from elements that lead to corrosion and oxidation. It also tends to be less expensive than stainless steel, but still maintains the shackle's strength and durability.

Stainless steel shackles are more corrosive-resistant and are therefore ideal for marine applications. Our stainless steel shackles are made of type 316 stainless steel, which is considered "marine grade." It contains molybdenum, which is resistant to ocean water mist or spray, so it's especially useful in extreme moisture conditions or in a high chloride environment. Type 316 stainless D-shackle equipment is ideal for sailing and yacht rigging uses.

Snap Shackle

A snap shackle is designed with a spring-activated mechanism so it can be used quickly and with one hand. These are handy for jobs where speed is important, or when an item needs to be hooked and unhooked often, but they are not recommended to secure heavy-duty loads.

Pin Types

The pin that locks a shackle can be a deciding factor on which shackle will work best for your job. We carry shackles with loose pins, captive pins, round pins, screw pins, and bolt type pins. Screw Pin Shackles are popular because they offer a pin that is easy to connect and disconnect. Captive Pin Shackles offer a pin that cannot be removed from the bow of the shackle, essential for various marine applications. This captive pin keeps the pin from accidentally falling out and into the water. Twisted Shackles offer a hook up from the same direction the pin is facing, making them ideal for certain limited hook up instances.
