Marine-Grade Straight Shackles (SC Type) for Rigging & Deck Use

Straight shackles, also known as chain shackles or SC shackles, are essential components in marine rigging and general deck operations. Designed for direct in-line loads, these shackles provide a secure and reliable connection between chains, ropes, wires, and other deck fittings. The straight shackle design offers maximum strength in straight-line tension applications, making them a preferred choice for lifting, towing, mooring, and lashing aboard commercial vessels and offshore installations.

Our straight shackles are manufactured from high-grade steel to meet the demanding conditions of the marine environment. Available in both galvanized carbon steel and stainless steel (316L) options, they offer excellent corrosion resistance against saltwater, UV exposure, and harsh weather. The screw pin or bolt-type closure ensures a safe and easy connection while allowing for quick assembly and disassembly. Each shackle is carefully inspected and tested to deliver reliable performance and full traceability as per international standards.

Whether you need a standard size for routine deck work or a heavy-duty shackle for critical lifting operations, this range of straight shackles (IMPA 231351) covers a wide spectrum of sizes and working load limits (WLL). Robust, versatile, and built to last, these shackles are a dependable addition to your ship’s rigging inventory.
