Cromox Master Links
Cromox master links are stainless steel oblong or pear-shaped links used at the top of multi-leg sling assemblies, the connection between the sling legs and the lifting hook or crane block. In a stainless steel rigging assembly, the master link is the seat for the hook. Cromox makes them from the same stainless steel as the rest of their hardware line, keeping the whole assembly corrosion-resistant from hook to sling fitting.
Cromox Stainless Steel Master Links for Corrosive Environments
A master link sits at the top of a sling assembly and takes the full assembly load, all sling legs terminate into it, and the lifting hook seats in the link's throat. That position makes the master link one of the highest-stress components in the assembly. In most industrial rigging, alloy steel master links are the standard. But in marine, food processing, pharmaceutical, offshore, and chemical environments, the corrosion argument shifts the choice to stainless.
Cromox master links are manufactured from stainless steel by the pewag Group in Austria. They are designed to work with Cromox's stainless chain and hardware line so the full assembly stays corrosion-resistant. The links are marked with WLL and manufacturer identification per EN 1677, the European standard for components of slings and lifting assemblies.
Master Link Applications by Environment
Marine and Offshore Rigging
Saltwater exposure corrodes alloy steel master links over time. Stainless master links in marine rigging maintain their integrity in saltwater environments for longer service intervals.
Food and Pharmaceutical Processing
Sling assemblies used in food plant lifting, handling tanks, vessels, and equipment in processing areas, are subject to washdown and cleaning agent exposure. Stainless master links are specified where contamination from surface rust is a concern.
Chemical and Petrochemical
Chemical exposure affects carbon and alloy steel surfaces. Stainless resists most common industrial process chemicals. Master links in chemical plant maintenance rigging, reactor lifts, and heat exchanger handling are candidates for stainless when the chemical environment warrants it.
Wastewater and Utilities
Sling assemblies working in water treatment plants, pump stations, and utility vaults operate in wet environments continuously. Stainless master links hold up where alloy would corrode.

Why Holloway Houston
Holloway Houston has supplied rigging hardware to Gulf Coast industrial operations for over 65 years. We stock Cromox stainless master links because offshore, marine, and chemical customers in the Houston area need corrosion-resistant hardware in their supply chain, not special-order lead times.
Holloway Houston also provides rigging inspection services. Our qualified inspectors examine master links, sling fittings, and hardware per applicable ASME standards.
Master Link Safety and Awareness
Master links are load-bearing components subject to inspection requirements under applicable OSHA and ASME standards. Key awareness points:
- Master links are marked with WLL and manufacturer identification per EN 1677. Links with illegible markings are removed from service.
- Visual inspection before each use covers cracks, deformation, and any change in link shape or throat opening.
- The master link WLL is the limiting capacity for the full sling assembly, the assembly's rated capacity is not higher than the master link's WLL.
- Proof test documentation and manufacturer certs are available from Holloway Houston with purchase.

Frequently Asked Questions
A master link is the top link in a multi-leg sling assembly. The sling legs, chain, wire rope, or synthetic, connect into the master link, and the lifting hook or crane block seats in the master link's throat. It takes the full combined load of all sling legs. Cromox master links are stainless steel, designed for corrosive environments.
Stainless steel master links are specified for environments where alloy steel corrodes, marine, offshore, food processing, pharmaceutical, and chemical applications. Stainless resists salt, cleaning agents, and most industrial process chemicals far better than alloy or carbon steel.
Cromox master links are manufactured per EN 1677, the European standard for components of slings and lifting assemblies. pewag Group, Cromox's parent company, holds ISO 9001 certification. WLL and manufacturer identification markings are per EN 1677 requirements.
WLL range by size is available through Holloway Houston. Call 1-888-496-4700 or request the Cromox product data sheet for specific WLL values by link style and size.
Stainless steel master links can be used with compatible rigging hardware as long as the WLL and physical dimensions are compatible with the mating components. For assembly matching questions, call Holloway Houston's rigging team at 1-888-496-4700.
