Stainless steel shackles with grub-screw locking for secure, reliable connections in marine, construction, and outdoor use. Key benefits Durable corrosion-resistant stainless steel resists rust and wear, extending service life in wet or harsh environments. Grub-screw design locks the pin in place for a more secure attachment than a plain pin, reducing the risk of accidental opening during lifting, towing, or tensioned rigging. Available in sizes from 5 mm to 10 mm with workload limits from 375 kg to 1225 kg, so you can pick the right strength for the job without overspecifying. Compatible with ropes and chains, offering flexible use across different rigging systems and hardware. How this product solves problems Replaces unreliable or worn connectors with a corrosion-resistant shackle that stays serviceable in marine and outdoor conditions. Prevents unexpected disconnection during towing, hoisting, or load restraint by using the grub screw to secure the pin. Lets you match shackle size to load requirements to improve safety and avoid under- or over-rated fittings. Specific applications Mooring and small-boat rigging: secure lines and chain to cleats, anchors, and fittings where corrosion resistance matters. Towing and load restraint: attach straps, chains, or rope for trailer loads, recovery straps, and light towing tasks within the stated workload limits. Construction and outdoor rigging: connect temporary safety lines, tarps, or hoists on job sites and campsites.
