Demystifying Synthetic Web Slings: Understanding Types and Selection

By: Dawnerz


Time to read 3 min

Synthetic web slings represent one of the most widely used lifting solutions in the market today. Their robustness allows them to shoulder substantial loads, and their versatility makes them invaluable across various industries and applications. What further distinguishes them is their cost-effectiveness, as easily replaceable slings can be acquired at reasonable prices.


It's not uncommon for customers seeking new synthetic web slings to be unfamiliar with the array of configurations available or to face challenges deciphering part numbers and specifications. This article aims to bridge that knowledge gap.

Types of synthetic web slings

Web slings come in an assortment of configurations, each tailored to specific lifting needs:


TYPE I: This web sling features a triangle fitting on one end and a slotted triangle choker fitting on the other end. It offers versatility, suitable for vertical, basket, or choker hitch applications.


TYPE II: Designed with a triangle fitting on both ends, this web sling is ideal for vertical or basket hitch use, providing reliable support.


TYPE III: This web sling boasts flat loop eyes on each end, positioned on the same plane as the sling body. It is commonly referred to as a flat eye and eye, eye and eye, or double eye sling.


TYPE IV: Similar to Type III, this web sling features loop eyes but with a twist. The loop eyes are turned to create a right-angle orientation to the sling body, making it known as a twisted eye sling.


TYPE V: Known as an endless web sling or grommet, this sling forms a continuous loop by joining the ends of the webbing with a load-bearing splice, providing exceptional durability.

Sizing Up Synthetic Web Slings: Length, Plies, and Width

The length of web slings can vary widely, with manufacturers offering standard lengths ranging from 2 feet to 30 feet. Customized lengths are also available to match specific application requirements. Measuring the sling length involves determining the distance between the top and bottom load-bearing points, with eye and eye slings measured from tip to tip of the eyes, and other configurations measured from the load-bearing point of any rings, hooks, or fittings.

Number of Plies

The number of plies in a synthetic web sling refers to the layers of webbing that constitute its body. They are commonly manufactured in 1, 2, 3, or 4 ply configurations. Increasing the number of plies enhances the sling's body strength proportionally.


For instance, when comparing the breaking strength of a 1-ply web sling to higher-ply alternatives:

  • 2-ply web sling - breaking strength of 2 times x.

  • 3-ply web sling - breaking strength of 3 times x.

  • 4-ply web sling - breaking strength of 4 times x.

Web Sling Width

Web sling width is a critical consideration when selecting a sling, as it directly affects load distribution and surface area contact. Standard sling widths typically range from 1 inch to 12 inches, while larger sizes are available for specialized applications.

Synthetic Web Sling Protection

Protecting synthetic web slings from wear, cuts, and abrasion is essential to prolong their service life. Several protective options can added.


Sling Wear Pads: These pads are sewn into the webbing material at specific wear points on the sling body or eyes.


Edge Guards: Sewn along the sling's edges, edge guards offer added protection at critical spots prone to abrasion or cutting.


Sleeves and Wraps: These accessories slide over or are sewn onto the sling body, shielding it from wear or cutting.

Choosing the Right Synthetic Web Sling

When transitioning from chain or wire rope slings, certain key considerations must guide your selection:

Armed with these considerations, you're now well-equipped to procure the correct synthetic web sling tailored precisely to your lifting application's demands.
