A 4 leg chain sling has four lengths of Grade 100 chain connected to a top master oblong link. Four legs is the maximum number of chain lengths available on one chain sling assembly. Compared to traditional 4 leg slings, adjustable slings have an additional adjustable mechanism that allows the operator to adjust the length of the chain legs as needed, without compromising working load limit.
End Fitting Options
Our 4 leg chain slings with chain shorteners are manufactured with your choice of end fitting on the long leg: sling hook, foundry hook, grab hook, or self-locking hook. However, custom chain slings are our specialty, so please give our sales team a call if you require different hardware.
Sling hook: also known as slip sling hooks, these large throat hooks are commonly used at the ends of chain slings and wire rope. They’re typically self-locking to avoid disconnect.
Self-locking hook: these hooks are designed to pivot in the middle and lock when lifting pressure is applied. They cannot be opened while lifted with your overhead lifting chains.
Foundry hooks: these are extra-large throat hooks that are used in unique situations that require a larger opening to manage loads.
Grab hook: these chain sling hooks have a small throat that attaches to the chain by slinging over the chain in-between links.
Oblong master link: An oblong shaped ring used at the top of chain slings.
Adjustable 4 Leg Sling Brands
We offer two trusted brands of adjustable 4 leg chain slings for you to choose from: Crosby and KWB. Both are made using alloy steel chain that’s 25% stronger than Grade 80 alloy chain. However, there are differences in both design, fitting hardware, and manufacturing origin.
Crosby Adjustable Slings
Crosby has been a leader in the rigging and lifting industry for years and takes no shortcuts when it comes to manufacturing chain and rigging hardware. Crosby chain slings are manufactured right here in the USA and expertly assembled by US Cargo Control.
Crosby’s line of adjustable chain slings feature the Crosby Eliminator, a revolutionary adjustable length chain sling fitting that literally eliminates the need for certain components in adjustable slings, that have been traditionally required. Other benefits of the Crosby Eliminator include a hinged design that prevents bending against a curved object, a wider and longer bail, and easier assembly due to the fact that you only need 2 fittings to build any adjustable sling, from single leg to quad sling.
KWB Adjustable Slings
KWB chain sling components are manufactured in Europe and expertly assembled into the high-quality adjustable chain slings you see here. KWB Grade 100 chain is easy to spot as it has a a signal violet varnish coat and a heavy powder coating that helps with corrosion resistance.
KWB 4 leg adjustable chain slings feature a built in shortener attached right to the master link. They have the traditional design and components that many are used to in the rigging industry.
Proof testing has been done on every link of chain to ensure its working load limit. To get your custom chain sling tested at the time of manufacture, it must be requested when the order is placed with our sales specialists. For an additional fee, we will proof test your sling and issue a certificate when requested at the time the order is placed.
All of our chain meets or exceeds the latest guidelines of the National Association of Chain Manufacturers (NACM), ANSI B30.9 standards and OSHA specifications.
