Adjustable 4 Leg - Grade 100

adjustable chain slings banner

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.

Proof Testing

Proof testing has been done on every link of chain to ensure its working load limit.
