Round Sling 20 ft Blue 4in - Heavy Duty Lifting Sling

In this review of the Round Sling 20 ft Blue 4in the bottom line is simple: this is a purpose-built lifting sling for industrial rigging where predictable capacity and easy handling matter. The reviewer found it most compelling for crews needing a strong, flexible sling with clear capacity markings and a low elongation cover that resists wear. It reads as a practical work tool rather than a consumer novelty, and the single biggest reason to buy is the combination of high rated capacities across vertical, choker and basket hitches that make it versatile on job sites.

Key Features

• Color coded cover: The blue cover makes rated capacity identification quicker on busy sites and helps keep inventory organized.
• High rated capacities: With a 21,200 lb vertical rating and a 42,400 lb basket rating, this sling covers heavy lifting needs without swapping gear.
• Double-wall polyester cover: The woven, seamless cover extends sling life by resisting abrasion while remaining soft enough to conform to loads.
• Low elongation: About 3% elongation at rated capacity gives predictable stretch under load, aiding precise rigging.
• Lightweight and easy to handle: The sling's construction makes it simple for one or two operators to rig, stow and move around a job site.

Who It's For

This sling is aimed at rigging professionals, warehouse teams and contractors who regularly lift heavy, irregular-shaped loads and need a sling that conforms to the load while offering high rated capacities for multiple hitch types. It suits shops that follow WSTDA specs and want color-coded slings to speed identification and reduce errors.

Those who should look elsewhere include users who require specialty fittings, custom lengths beyond the shown 20 ft, or slings rated for continuous exposure to harsh chemicals - this sling is optimized for general industrial use and abrasion resistance rather than chemically resistant applications.

Pros & Cons

Pros

• High multi-hitch rated capacities provide versatility across vertical, choker and basket configurations.
• Durable double-wall woven polyester cover resists abrasion and extends service life.
• Low elongation and soft, lightweight feel make rigging predictable and handling simple.

Cons
