In any multi-leg sling assembly, the master link is the critical connection between your rigging and the crane hook. Load angles, leg configuration, working load limit requirements, and hook geometry converge at this single component. Empire Rigging supplies forged alloy master links engineered for high-capacity, overhead lifting environments where strength, dimensional accuracy, and consistency matter.
Whether you are building new chain slings, replacing hardware in the field, or fabricating custom lifting assemblies, we stock the master link configurations professionals rely on daily.

Oblong Master Links
Oblong master links are the industry standard for 2, 3, and 4-leg sling assemblies. The elongated inside length allows multiple sling legs to gather cleanly while maintaining proper seating in crane hooks.
These links are commonly used in:
• Alloy chain sling assemblies
• Wire rope bridle slings
• Synthetic multi-leg slings
• Engineered lifting devices
The oblong shape helps maintain alignment under load while accommodating larger hook throats. Available in a range of sizes and working load limits, oblong master links are the backbone of most multi-leg lifting configurations.
Pear Shaped Master Links
Pear shaped master links are engineered for applications requiring a narrower top section and a wider bottom radius. This design can improve hook fit and optimize leg alignment in certain sling configurations.
They are often selected when:
• Hook throat dimensions are limited
• A tighter top connection is preferred
• Building compact 2-leg assemblies
• Managing specific center-of-gravity challenges
The geometry of a pear shaped link can reduce unnecessary movement at the hook interface while maintaining full rated capacity.
Round Master Links
Round master links offer a symmetrical, circular connection point ideal for single-leg slings and lighter-duty applications. Their uniform shape allows smooth rotation under load and simplified alignment during attachment.
Common uses include:
• Single-leg chain slings
• Wire rope assemblies
• Fabrication and maintenance lifts
• Compact rigging setups
For straightforward vertical lifts or simple connection points, round master links provide a clean, efficient solution.
Master Link Sub-Assemblies
Master link sub-assemblies are designed for multi-leg bridle slings where leg separation and load distribution are critical. A primary master link connects to the crane hook, while two secondary links provide dedicated attachment points for sling legs.
This configuration:
• Reduces crowding at the top connection point
• Improves leg orientation and spacing
• Enhances load balance in 3 and 4-leg assemblies
• Simplifies inspection and maintenance
Sub-assemblies are especially valuable in higher-capacity lifts where clean geometry and consistent leg angles directly affect sling performance and working load limit calculations.
Engineered for Strength, Traceability, and Compliance
Empire Rigging master links are forged from high-strength alloy steel and manufactured to meet applicable industry standards for overhead lifting. Each component is designed with proper heat treatment and dimensional control to ensure consistent performance under load.
When building or repairing sling assemblies, it is critical that all components match in grade and working load limit. Our master links are clearly marked and sized to integrate seamlessly with compatible chain grades and sling hardware.
Proper selection and inspection are essential. Always verify:
• Working load limit for the intended sling configuration
• Compatibility with crane hook dimensions
• Correct grade matching with chain or sling components
• Absence of deformation, elongation, or wear before use
Selecting the Right Master Link for Your Application
Choosing the correct master link is not just about capacity. Professionals should consider:
• Number of sling legs
• Lift angle and resulting load factors
• Hook throat opening and saddle size
• Required inside length and width dimensions
• Clearance for shackles or connectors
In multi-leg bridle slings, maintaining proper leg angle directly impacts load distribution. The master link must accommodate connectors without side loading or binding, which can compromise performance and inspection clarity.
If you are assembling custom slings or engineered lifting solutions, our team can assist with proper hardware selection to ensure your assembly meets operational and safety requirements.
