Anchor, Bow, Chain, and D Shackles
With a variety of chain shackles for straight pulling, anchor shackles for multi-dimensional pulls, lifting shackles, and many more stainless steel D shackles and bow shackles, we have the equipment you need to get the job done.
As 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, and 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 shackles and bow shackles 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. The rounded design of anchor shackles and bow shackles allow them to take loads from many directions without developing significant side load. The larger loop shape of an anchor shackle or bow shackle does reduce its overall strength, but it is also able to handle a larger strap.
Chain shackles are also known as D-shackles, d shackles, or “dee shackles.” Both refer to the “D” shape design. A d-shackle is narrower than a bow or anchor shackle and generally have a threaded pin or pin close. The smaller loop is designed to take high loads primarily in line. Side and racking loads may twist or bend a D or chain shackle.
Both anchor/bow and chain/d-shackles come with different pin options as well.
Galvanized shackles vs. stainless steel shackles
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 thin coating of zinc oxide to protect the steel from elements that lead to corrosion and oxidation. Galvanized is also a great value as it 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.” Type 316 marine grade stainless steel contains molybdenum, which makes it resistant to ocean water mist or spray, so it’s especially useful in extreme conditions or moisture or in a high chloride environment. Type 316 stainless D shackle equipment is ideal for sailing and yacht rigging uses.
As a variation on the stainless steel d 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. Our stainless steel snap-style shackles are in type 316 stainless steel for extra corrosion resistance.
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 which is essential in 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.
Shackles by brand: Crosby shackles & Chicago Hardware shackles
Our wide range of shackles includes both domestic and import options. While the majority of our customers prefer Made in the USA shackles, we offer a variety of import shackles as well for those that would like a more economical choice. Please keep in mind that imported shackles must also meet federal specifications, just as shackles that are manufactured in the United States.
All of our shackles- both domestic and imported- are embossed with working load limit information for easy and fast identification.
With so many varieties and names of similar items, misspellings and specialty terms are common. You may also see shackles listed as shakles, shakle, shacles, schackles. Rigging shackles and recovery shackles are also commonly used in the industry.
