Factor 55 Ultrahook 00250-05 Closed System Winch Hook — 16k Load, 48k Shackle Pin, USA Made

Ultrahook 00250-05: Closed System Winching for Off‑Road Confidence

When you’re on rugged trails, you want a hook that blends speed, security, and simplicity. The Factor 55 Ultrahook 00250-05 is designed with a low profile that still delivers heavyweight performance. A unique, industry‑first closed system shackle mount is machined directly into the hook body, and the latch pin to lock the safety latch is stored inside the hook for quick, confident setup. This design supports a true closed loop during winching, which can help keep loads contained as conditions shift along the line.

Beyond the closed system design, the Ultrahook includes practical features that matter in the field. Integrated EPDM rubber pads cushion the fairlead and prevent metal-to-metal contact that can cause rattling, while finger grips encourage proper Hook Up orientation for fast, repeatable use. The result is a compact, high‑strength option for winching with both reliability and ease in mind.

What makes a closed system winching approach worth considering?

• All‑hardware closed loop: The system is designed to keep the load contained with a secure, continuous path.
• Stored latch pin: A built‑in pin locks the safety latch for a true closed system while you work.
• Protective pads: EPDM pads shield the fairlead and reduce rattling during movement and vibration.

Materials, build, and key specs

• Lightweight, CNC machined 7000‑series aluminum for strength with minimal mass.
• Maximum load: 16,000 lbs; Ultimate throat opening: 31,000 lbs; Shackle pin mounting: 48,000 lbs.
• Line compatibility up to 3/8” diameter; up to 3” thick when folded flat.
• Includes 5/8” diameter aerospace‑grade titanium doubleshear pin; weight around 32 oz.
• Designed, engineered, and made in the USA; optimized for rugged off‑road use.

Ease of use and versatile mounting

• Easy installation with a shackle mount hole machined into the hook body; accepts common screw pins and soft shackles up to 1/2”.
• Can function as a conventional hook or a shackle mount, with no rope splicing required.
• Double shear pin design suits both steel and synthetic winch rope, supporting flexible setups.

Real‑world scenarios

The Ultrahook is well suited for off‑road recovery, trail rides, and overland adventures where quick hook‑up and secure load containment matter. Its compact form fits tighter rigging while the robust construction handles demanding pull loads. The combination of a closed system and protective pads helps reduce rattling and wear in challenging environments, making it a practical upgrade for serious enthusiasts.

While these features align with high‑demand use cases, individual results can vary by setup and conditions. Consider this hook as a potential upgrade to improve usability, safety, and reliability in the right off‑road scenarios.
