Synthetic Endless Round Slings (Polyester)
Round slings are high-performance, endless-loop lifting slings constructed from multiple high,tenacity polyester core yarns encased in a tough, woven polyester jacket. At Holloway, we don’t just distribute rigging,we build it. We manufacture our polyester round slings in-house at our Houston, Texas facility, which stands as the nation's largest single,location sling shop and testing center.

Polyester Round Slings — Manufactured by Holloway
Our round slings are engineered to meet and exceed ASME B30.9 and EN 1492-2 standards. Every sling we build is equipped with a unique serial number, a permanent rated capacity tag, and industry,standard color-coded jackets for instant identification. Because they conform to the shape of the load and offer superior flexibility, our round slings are the preferred choice for lifting delicate or irregularly shaped objects. With a Working Load Limit (WLL) range spanning from 2,600 lbs to over 100,000 lbs, we manufacture the exact capacity you need for everything from light plant maintenance to the most massive industrial picks.
How Round Slings Are Constructed
Understanding the anatomy of a round sling reveals why it is often superior to flat web slings for heavy rigging. An Holloway manufactured round sling consists of three critical components:
-
The Load-Bearing Core: The true strength of the sling lies in its internal core yarns. These consist of multiple continuous loops of high,tenacity polyester yarn that carry 100% of the load. We ensure there are no knots or splices in this load-bearing path, providing total strength consistency.
-
The Protective Cover (Jacket): A durable, woven polyester sleeve surrounds the internal yarns. While the cover does not carry the load, it protects the core from abrasion, UV degradation, and environmental contaminants.
-
Color-Coded Identification: Holloway follows the industry-standard color-coding system. This allows your rigging crew to verify the round sling color code and capacity at a glance, improving site safety and efficiency.
Round Sling Capacity Chart — Color Code Guide
The table below details the rated capacities for our standard endless round slings across the three primary hitch configurations.
| Color | Vertical Hitch | Choker Hitch | Basket Hitch (90°) |
|---|---|---|---|
| Purple | 2,600 lbs | 2,100 lbs | 5,200 lbs |
| Green | 5,300 lbs | 4,200 lbs | 10,600 lbs |
| Yellow | 8,400 lbs | 6,700 lbs | 16,800 lbs |
| Tan | 10,600 lbs | 8,500 lbs | 21,200 lbs |
| Red | 13,200 lbs | 10,600 lbs | 26,400 lbs |
| White | 16,800 lbs | 13,400 lbs | 33,600 lbs |
| Blue | 21,200 lbs | 17,000 lbs | 42,400 lbs |
| Orange | 25,000 - 100k+ lbs | 20k - 80k lbs | 50k - 200k lbs |
Safety Note: Choker hitch capacity is approximately 80% of vertical. Basket capacity is 200% of vertical only when the lift angle is exactly 90 degrees. Always verify the physical capacity tag on your HHI sling before rigging.
Round Slings vs. Web Slings
While both are synthetic, the construction of a round sling offers distinct advantages over flat web slings:
Conformity: Round slings are tubular and flexible, allowing them to conform to the shape of cylindrical or irregular loads better than flat webbing.
-
Durability: Because the load-bearing yarns are protected by an outer jacket, round slings are more resistant to UV and surface abrasion.
Weight: At equivalent capacities, round slings are generally lighter and more compact, making them easier for riggers to carry and position.
Round Sling Applications
Holloway round slings are the primary lifting tool for dozens of industries:
-
Construction & Steel Erection: Ideal for pipe bundles and structural steel.
-
Oil & Gas: Used extensively in Houston fabrication yards for valves and pressure vessels.
-
Manufacturing: Perfect for motor and pump installation where surfaces must not be marred.
-
Marine & Shipbuilding: Polyester core yarns maintain their full capacity even when wet, unlike nylon.

Frequently Asked Questions
A round sling is an endless-loop lifting device made of polyester core yarns encased in a protective sleeve. It is designed to be lightweight, incredibly strong, and gentle on the load surface.
The colors indicate capacity per ASME B30.9. For example, Purple is 2,600 lbs vertical, while Green is 5,300 lbs. This allows for quick, visual safety checks in the field.
Inspect the outer cover for any holes, tears, or snags. If the jacket is damaged enough to show the internal core yarns, the sling must be removed from service immediately.
Polyester round slings have a maximum operating temperature of 194°F (90°C). For high-heat environments, Holloway recommends switching to chain or wire rope slings.
Yes. Round slings are actually superior for choker hitches because their tubular shape handles the bend radius better than flat web slings.
Unlike nylon, polyester does not lose strength when wet, making our round slings ideal for marine and offshore applications.
Absolutely. We stock standard lengths from 3' to 30', but we can manufacture custom round slings to any length required by your specific project.
Yes. Every Holloway sling undergoes a rigorous proof-load test at our Houston facility and is shipped with a unique serial number and certification.
