Canada’s Unirope Limited has expanded its rigging solutions with the addition of Helix and Onyx synthetic roundslings from long-time partner Slingmax Rigging Solutions. These new offerings complement Unirope’s wide range of high-performance rigging products and are tailored to meet specific lifting needs across industries.
Manufactured to order, Helix and Onyx are designed for both standard and specialized applications. Helix features Slingmax’s proven K-Spec core yarn, Rifled Cover Technology, and a compact HMPE jacket ideal for tight clearances. Onyx, a more economical option, uses 100% HMPE core fibers and dual-layer protection, delivering safety and performance at a competitive price point.

Unirope will also stock Slingmax’s Spider Sleeve, Covermax, and Cornermax protective products. These enhance durability and safety through abrasion and cut resistance—key for demanding rigging environments.
“With Helix and Onyx, we’re addressing gaps in the market while boosting safety and reliability,” said Unirope President Justin Brown. “This partnership with Slingmax continues to push innovation in rigging technology.”
John Ketchum, Vice President at Slingmax, emphasized K-Spec’s rigorous testing and traceability, adding: “K-Spec delivers strength comparable to wire rope with 90% less weight, setting a new standard for high-performance synthetic slings.”
Unirope’s products comply with ASME, Cordage Institute, and WSTDA standards, ensuring industry-leading quality and performance for lifting professionals in Canada, the U.S., and Europe.
