A round sling jacket keeps core yarn strands together but does not provide complete protection for the core material.

When it comes to round slings, a jacket, sleeve, or cover primarily keeps the core yarn strands together. However, it’s important to note that a jacket is not a protection sleeve and cannot entirely prevent damage to the core material. While the suitable jacket material can help prevent early deterioration, it won’t offer complete protection. To help protect your round sling, we offer four different options for covers:

Bio-Based Dyneema® Jacket

Dyneema® is a highly durable material widely used across various industries due to its excellent resistance against cuts, abrasions, and punctures. While white is the standard color for Dyneema®, other colors are available upon request. Some of the advantages of using Dyneema® include its high durability and stretchability, as well as its ability to protect the payload without causing any damage. With a proven track record in numerous industries and applications, Dyneema® is a reliable choice for a wide range of lifting and rigging needs.

Cordura Jacket

For superior strength and performance in high-performance gear, Cordura® is the go-to choice. Cordura® is known for its exceptional resistance to abrasions, tears, and scuffs. Available in sleek black, this super-durable fiber is a primary ingredient in many heavy-lift round slings.

A jacket may not provide complete protection, but choosing the right one can make all the difference in prolonging the life of your round sling.

Polyester Jacket

Polyester jackets are a popular and budget-friendly choice for lifting applications that require reliable performance across a wide temperature range (-40 °C to +100 °C). These jackets are made from high-quality 100% polyester yarn and come in a distinctive orange color. However, it’s important to note that polyester tends to absorb water, which can impact performance in certain conditions.

Extreema® XL Jacket

The Extreema® XL jacket is a protective covering designed to shield slings from contact with sharp edges. It offers superior cut, puncture, and tear resistance, making it ideal for applications where slings are frequently exposed to harsh or abrasive surfaces. The jacket can help prolong the life of the sling by preventing damage to the core yarn strands and reducing the need for repairs or replacements.
