Double Eye Lifting Slings | Industrial Polyester Sling Solutions

Double eye lifting slings represent one of the most versatile and widely used configurations in industrial rigging and lifting operations. As of 2026, these slings remain the industry standard for applications requiring secure attachment points at both ends, making them essential for construction, manufacturing, transportation, and heavy equipment handling. Our double eye polyester webbing solutions are manufactured to meet rigorous performance standards, with working load limits ranging from 1,500 lbs to 40,000 lbs depending on width and construction. Whether you are sourcing for a single project or establishing a long-term supply relationship for bulk procurement, understanding the specifications, applications, and selection criteria for double eye lifting slings is critical to ensuring safety and operational efficiency.

What Are Double Eye Lifting Slings?

Double eye lifting slings, also referred to as eye-and-eye slings, are continuous loops of woven polyester webbing with finished eyes formed at both ends. Unlike single eye slings that feature one loop and one hook, or basket hitch configurations that rely on a single continuous loop, double eye slings provide two secure attachment points for versatile rigging setups.

The construction process involves weaving high-tensile polyester yarns into a flat, dense fabric, then forming permanent eyes at each terminus using steel eyelet end fittings. These fittings are crimped or riveted to match the webbing's working load limit, ensuring the attachment point does not become the weak link in the lifting assembly.

Key Specifications & Performance Data

Our double eye polyester webbing is available in widths from 1 inch to 12 inches, with corresponding working load limits that scale proportionally. The following specifications reflect current industry standards for industrially woven polyester lifting slings.

Double Eye Polyester Webbing Specifications

All slings are manufactured from industrially woven polyester with a minimum safety factor of 7:1 for vertical lifting applications. The webbing construction utilizes high-density weave patterns that resist abrasion, UV degradation, and chemical exposure common in industrial environments.

Double Eye vs. Other Lifting Sling Configurations

Selecting the correct sling configuration is critical for safe and efficient lifting operations. Double eye slings offer distinct advantages over single eye and basket configurations in specific applications.

Configuration Comparison

Compared to loose webbing supplies that require on-site eye formation, pre-assembled double eye lifting slings eliminate field fabrication time and ensure consistent eye strength. Our slings are manufactured with precision-crimped steel eyelets that match the webbing's working load limit, providing reliable performance from first use.

Applications & Industry Use Cases

Double eye lifting slings are utilized across diverse industries where reliable load attachment and detachment is required. Their versatility stems from the ability to connect to hooks, shackles, and other rigging hardware at both ends.

Primary Applications

For specialized applications requiring marine-grade hardware, our [316 Marine Grade Ratchet Strap](/products/316-marine-grade-ratchet-strap/) collection complements double eye sling setups with corrosion-resistant stainless steel components suitable for saltwater environments.

Frequently Asked Questions

What is the difference between double eye and single eye lifting slings?

Double eye slings feature finished eyes at both ends, allowing attachment to hardware on both sides of the load. Single eye slings have one finished eye and one open end, designed for hook-to-eye connections. Double eye configurations provide greater versatility for rigging setups requiring symmetric attachment points.

How do I determine the correct double eye sling size for my application?

Select sling width based on load weight, lifting angle, and configuration. A 2-inch double eye sling has a WLL of 3,000 lbs in vertical lifting. Always consult the specification table and consider a safety factor of at least 7:1 for personnel safety. For angled lifts, capacity decreases based on the angle from vertical.

Are double eye polyester slings suitable for outdoor use?

Yes, polyester webbing offers excellent UV resistance compared to nylon. Our double eye slings are suitable for outdoor construction, marine, and industrial applications. However, prolonged sun exposure will gradually reduce tensile strength. Inspect slings regularly and replace if UV degradation is visible.

What is the minimum order quantity for bulk double eye sling purchases?

Standard configurations are available for immediate shipment with no minimum order. For custom colors, lengths, or specialized hardware, typical MOQ ranges from 100 to 500 pieces per SKU depending on specifications. Contact our sales team for project-specific quoting.

Do your double eye slings meet WSTDA and international standards?

Yes, all lifting slings are manufactured in ISO 9001-certified facilities and comply with WSTDA standards. Each sling is marked with WLL, size, and compliance information. Test reports and certification documentation are provided with bulk orders.
