Key specifications

• Lifting‑rated synthetic soft shackle with 3,300 lbs Working Load Limit

• 4" working diameter for secure connections to hooks, pad eyes, lifting lugs, and structural members

• Rope body made from high‑strength HMPE synthetic fiber with a protective sleeve for abrasion and UV resistance

• Designed to meet or exceed ASME B30.26 requirements for rigging hardware used in lifting operations

Design and safety

• Excellent strength‑to‑weight ratio compared to steel shackles, reducing operator fatigue and the risk of dropped heavy hardware

• Soft, flexible body wraps cleanly around anchor points, helping reduce point‑loading, metal‑to‑metal contact, and damage to painted or delicate surfaces

• LockJaw closure system keeps the shackle securely closed under load while remaining quick and simple to open and re‑rig between lifts

• If overloaded to failure, the synthetic shackle is designed to fall safely rather than violently recoil, helping reduce injury risk versus traditional steel shackles

• Corrosion‑resistant, UV‑resistant construction for long service life in outdoor, marine, and harsh‑environment operations

Made in the USA

• Manufactured in the USA with tight quality control and material traceability

• Engineered with a robust design factor behind the stated WLL to support lifting and other critical rigging tasks
