Stainless Steel Thimble Eye Protection Rope Sleeve Series

304/316 Stainless Steel Wire Rope Thimble Series (Heart-shaped/Thimble - Standard/Cat Ear/Rabbit Ear Styles - 6mm/8mm/10mm - Anti-wear and Anti-crush Eye Protection - Patented Design)

High-strength stainless steel thimbles designed for industrial rigging, rope rescue, rock climbing eye loops, and steel wire rope systems. Placed inside the loop of a rope or cable, they maintain a uniform arc for the eye, completely preventing direct friction between the rope and connected metal hardware, while eliminating structural crushing and metal fatigue caused by bending radii that are too small under heavy loads.

The series offers a "Classic Standard" style and a "Cat Ear/Rabbit Ear Reinforced" style with a patented design—the protruding anti-slip ears on both sides effectively prevent the main rope or steel cable from slipping out of the groove during vibration, swaying, or when not under full tension. Compatible with various braided nylon static ropes, dynamic ropes, and high-strength steel wire ropes.

• Maintains Rigid Eye Arc: Prevents steel cables and fiber ropes from being excessively squeezed or folded by master links or hooks under load, preserving the rope's rated breaking strength.

• Patented Anti-Slip Ear Structure (Cat Ear/Rabbit Ear Styles): Raised ear-shaped limit wings on both sides securely wrap and lock the rope body in place, preventing the rope from slipping or shifting out of the guide groove due to shaking or impact.

• 304 / 316 Austenitic Stainless Steel Casting: The 304 model is suitable for general industrial environments, while the 316 marine-grade stainless steel model features superior resistance to salt spray and seawater corrosion, making it ideal for high-humidity outdoor settings, maritime engineering, and caving operations.

• Deep, Smoothly Polished Guide Groove: The curved rope guide groove is smoothly rounded and free of burrs, preventing fiber sheath abrasion and effectively isolating wear.

• Wide Diameter Compatibility: Covers common rope sizes including 6mm, 8mm, and 10mm, ensuring a tight fit for both braided safety ropes and heavy-duty steel wire ropes.
