A 3/4‑inch shackle is a heavy‑duty rigging connector commonly used in live event production to attach motors, truss, spansets, and other load‑bearing hardware in a safe, controlled way. In entertainment rigging, shackles serve as primary connection points because they offer high working‑load limits, predictable strength ratings, and secure pin‑style closures that resist vibration and shock loads, which is critical when suspending truss, lighting, audio arrays, or scenery above performers and audiences. These qualities make 3/4‑inch shackles standard hardware in stage rigging kits, trusted for their durability, strength, and reliability.
