Crosby Chain Accessories
Chain sling legs need a grab hook at the load end, a master link at the crane end, and often a shortening clutch or intermediate link when the sling length needs field adjustment. Crosby produces the full range of chain accessories to outfit alloy chain slings for industrial lifting service.
About Crosby Chain Accessories
Chain sling accessories are the hardware that converts a length of alloy chain into a complete sling assembly, grab hooks that engage chain links at the load, master links that connect to the crane hook at the top, shortening clutches that shorten individual legs in the field, and connecting links that join chain lengths to hardware.
Crosby chain accessories are grade-rated to match Grade 80 (alloy) and Grade 100 chain sling systems. The grade rating matters because mixing accessory grades can introduce a weak link into the assembly, a Grade 60 hook on a Grade 80 chain sling leg limits the assembly to Grade 60 capacity at that end.
Chain sling hardware falls under ASME B30.9-2018 (Slings) and the NACM Welded Chain Specifications, which govern design factors, WLL ratings, and marking requirements for chain sling components.

Types of Crosby Chain Accessories
Grab Hooks
Grab hooks engage chain links for the load-end connection on chain sling legs. The narrow throat profile seats a chain link without allowing the link to slip through. Crosby Grade 80 and Grade 100 grab hooks are the standard load-end hardware on alloy chain slings in industrial lifting.
Shortening Clutches
Shortening clutches allow the length of individual chain sling legs to be adjusted in the field without removing and replacing chain. The clutch body engages chain links at multiple positions, providing incremental shortening without tools. Used on multi-leg slings where leg lengths need to match the load geometry.
Connecting Links and Coupling Links
Connecting links and coupling links join chain lengths to each other or to hardware end fittings. They're used to repair broken chain sections, extend sling lengths, and connect chain to master links and hooks that aren't designed for direct chain engagement. Grade-rated to match the chain assembly WLL.
Chain Sling Hooks
Chain sling hooks, including slip hooks, sling hooks, and eye hooks for chain attachment, provide the crane-end and load-end connection hardware for chain sling assemblies beyond the standard grab hook. Crosby produces these in Grade 80 alloy steel to match chain sling capacity ratings.
Chain Accessory Sizes and Working Load Limits
Crosby chain accessories are sized to match standard alloy chain sizes for Grade 80 and Grade 100 chain sling systems. Chain size is measured by link wire diameter — common sizes include 7/32", 9/32", 3/8", 1/2", 5/8", 3/4", and 1" for industrial chain sling assemblies.
Grade-Rated :
- Grade 80 (alloy): Standard industrial chain sling rating.
- Grade 100: Higher capacity per link diameter than Grade 80.
Marking :
- Grade designation and manufacturer identification per ASME B30.9-2018 (Slings) and NACM standards.
Why Crosby for Chain Accessories
Chain accessory grade matching is non-negotiable in assembly WLL calculations, the assembly is only as strong as its lowest-rated component. Crosby's Grade 80 and Grade 100 chain accessories carry grade markings and WLL values per ASME B30.9-2018 (Slings) and NACM Welded Chain Specifications, so the assembly documentation is consistent from chain to hook.
The forged alloy steel on Crosby grab hooks and shortening clutches matches the fatigue life of the chain they connect to, which matters on assemblies that see high cycle counts in production and maintenance lifting.
Holloway Houston also offers rigging inspection services. Our qualified inspectors examine chain slings and accessories per ASME B30.9-2018 (Slings) and OSHA standards.

Crosby Chain Accessory Applications by Industry
- Industrial Rigging : Chain sling assemblies for maintenance, machine lifts, and crane work where alloy chain slings are the specified rigging medium.
- Steel Mills and Foundries : High-temperature rigging environments where alloy chain sling accessories outperform synthetic rigging materials.
- Mining and Aggregates : Heavy-duty chain sling rigging for mill maintenance, conveyor work, and equipment lifts in abrasive environments.
- Offshore and Marine : Alloy chain sling assemblies for platform maintenance and marine work where synthetic slings are excluded by temperature or environment.
- Shipbuilding : Chain sling rigging in fabrication yards where chain's abrasion and heat resistance is the reason it's specified over synthetic alternatives.

Chain Accessory Safety and Awareness
Chain sling accessories fall under ASME B30.9-2018 (Slings) and NACM Welded Chain Specifications. OSHA 1910.184 references chain sling hardware in general industry; OSHA 1926.251 addresses rigging hardware on jobsites.
Key awareness points for chain accessories in service:
- Chain accessories are grade-rated. Mixing Grade 80 chain with Grade 60 accessories limits the assembly WLL to the lower-rated component, per ASME B30.9-2018 (Slings), the assembly WLL is determined by the component with the lowest rated capacity.
- Pre-use inspection of chain accessories covers the grab hook throat for deformation, the shortening clutch body for wear and full engagement, and connecting link welds for cracks.
- A chain accessory with deformed, cracked, or worn bearing surfaces warrants removal from service per ASME B30.9-2018 (Slings) inspection criteria.
- Grab hooks are not rated for side-loading beyond the hook's rated side-load capacity, if any. Standard grab hook WLL is in-line.
Frequently Asked Questions
Grade 100 chain and accessories carry a higher WLL per link diameter compared to Grade 80, approximately 25% more capacity at the same chain size. Grade 80 is the standard alloy chain sling specification for most industrial lifting. Grade 100 is specified where the higher capacity per given chain weight is required. Accessories match the chain grade to maintain the assembly's rated WLL.
Chain sling accessories fall under ASME B30.9-2018 (Slings) and the NACM Welded Chain Specifications, which govern design factors, WLL marking, and inspection requirements. OSHA 1910.184 and OSHA 1926.251 reference chain sling hardware in general industry and jobsite use.
Holloway Houston stocks Crosby chain accessories including grab hooks, shortening clutches, and connecting links in Houston with same-day shipping on in-stock items. Call 1-888-496-4700 to confirm availability on a specific chain size and grade.
Shortening clutches are sized to specific chain link dimensions. Using a shortening clutch on chain that's too small for the clutch body can allow the chain to slip through rather than engage the clutch. Crosby's catalog provides the chain size compatibility for each shortening clutch model.
