K2 Heavy Duty Stub-end Thimble

No.604013

The H-Lift K2 Heavy Duty Stub-end Thimble is a rugged wire rope fitting designed with a shorter, open profile to provide reliable cable eye protection while allowing easier attachment to specialized connectors.

  • Features a unique stub-end design that allows for easier connection to various rigging hardware compared to standard teardrop thimbles.
  • Forged from high tensile or superior mild steel and hot-dipped galvanized for maximum corrosion resistance in outdoor and marine environments.
  • Available in the standard K2 model or the reinforced K2-B model, which includes a welded center gusset to prevent eye crushing under extreme loads.
  • Rated for reliable performance across a wide temperature range from -20°C to +200°C in demanding industrial and rigging applications.

Technical Data

The K2 Heavy Duty Stub-End Thimble is specifically engineered for high-stress industrial and maritime rigging. Manufactured from forged high-tensile steel, it provides exceptional structural integrity and prevents wire rope eyes from collapsing under extreme tension. Its unique "Stub-End" geometry offers a shorter profile, making it the ideal choice for connecting wire rope slings to large-diameter anchor points and shackles.

⚠️ SAFETY WARNING: TERMINATION INTEGRITY.
Ensure the thimble groove size exactly matches your wire rope diameter. Improperly sized thimbles can cause the rope to pinch or slip. Termination breaking strength depends entirely on the swaging or clipping method used. PERFORMANCE RATED: -20°C to +200°C.
🏗️ Extreme Duty Design

The K2 series is engineered for the most demanding environments. It provides significantly higher resistance to deformation than standard commercial thimbles, ensuring a stable eye loop even under peak dynamic loads.

📐 Stub-End Geometry

Features a specialized open throat profile. This facilitates easier attachment to large connectors and specialized anchor points that would otherwise be restricted by traditional teardrop thimbles.

🛡️ Forged Strength & Protection

Manufactured from forged superior mild steel and hot-dip galvanized. This process creates a thick, durable zinc coating that is essential for preventing rust in severe saltwater and coastal settings.

🔄 Wire Eye Protection

Acts as a hardened, permanent barrier that prevents the steel wire cable from fraying or pinching when bearing against a shackle pin. This significantly extends the safe operational life of your rigging assemblies.

Q: What is the main difference between a K2 and a K2-B thimble? [Image comparing standard K2 thimble vs K2-B thimble with welded reinforcement gusset] A: The standard K2 is a heavy-duty stub-end thimble for general high-stress industrial rigging. The K2-B version features a gusset (a welded reinforcing steel plate) in the center of the thimble to provide maximum protection against the eye being crushed or flattened under extreme industrial pulling loads.
Q: Why use a "stub-end" thimble instead of a teardrop thimble? A: Stub-end thimbles are preferred when you need more clearance or a shorter profile to attach the wire rope eye to larger diameter pins, heavy-duty shackle bodies, or specialized rigging connectors that physically would not fit inside the narrow apex of a traditional teardrop-shaped eye.
