The H-Lift Stainless Steel Extra Heavy Duty Wire Rope Thimble U.S. Type meets Federal Specification FF-T-276B Type III standards for maximum protection in high-load, corrosive environments. Drop-forged or precision-cast from AISI 316 marine-grade stainless steel with reinforced thick sidewalls, these thimbles prevent crushing and wear in critical applications like towing, hoisting, and offshore rigging, available in sizes from 1/4" to 1".
H-Lift Extra Heavy Duty US Type Wire Rope Thimbles are modeled after the G-414 pattern, featuring significantly thicker steel walls for maximum strength. Specifically engineered for overhead lifting and marine towing, these thimbles provide a rigid, heavy-gauge liner that prevents cable eyes from crushing under extreme tension.
Preferred for overhead lifting and high-stress industrial rigging due to its high resistance to deformation and load-bearing capacity.
Superior corrosion resistance compared to galvanized thimbles, making it the top choice for saltwater towing and offshore applications.
Features thick-walled construction that maintains its shape even when used with wire ropes tensioned near their breaking limit.
Meets the dimensional and performance requirements of US Federal Specification FF-T-276b Type III.
Q: Why choose a G-414 thimble over a G-411 thimble?
A: The G-414 (Extra Heavy Duty) has much thicker material walls. It is required for heavy lifting, shock loads, or applications where wire rope is tensioned to high percentages of its breaking strength.
Q: Is this thimble suitable for overhead lifting?
A: Yes. When integrated with properly rated fittings, the G-414 pattern is the standard choice for overhead lifting assemblies because it will not collapse under heavy load.

Always ensure the thimble size matches the wire rope diameter exactly. A mismatched thimble can lead to premature wire rope fatigue or the thimble slipping out of the eye. For high-cycle dynamic loads, regular inspection for groove wear is highly recommended.
