labwork 5/16 RTJ Cluster Hooks Set G70 - 4‑Pack Forged Towing Frame Hooks, 5,400 lb WLL, Multi‑Fit

labwork 4 Pack 5/16 RTJ Cluster Hooks are Grade 70 forged cluster hooks that combine three hook types into one heavy-duty towing connector for car haulers, tow trucks, and wreckers.

If you need sturdy, versatile frame hooks for vehicle transport or recovery, this labwork RTJ cluster hook set delivers a compact, multi-hook solution built for professional towing applications. Each cluster incorporates multiple hook profiles engineered to fit common frame holes so you can adapt to different vehicle frame designs without swapping hardware on the fly. The set is heat treated and rated to handle the typical loads encountered in towing and hauling operations, making installation and crossover compatibility more efficient.

How do these RTJ cluster hooks save time during towing operations?

By combining three distinct hook shapes into a single cluster, these hooks reduce the need to carry and switch separate hook styles. That means faster attachment and detachment when loading vehicles or securing a haul, letting crews work with fewer parts and less downtime.

• Three-hook cluster adapts to multiple frame hole designs
• Single-piece installation instead of several separate hooks
• Reduces time spent searching for matching hook styles
• Compact design minimizes equipment clutter in the truck

What are the strength and safety specifications of the set?

These labwork RTJ cluster hooks are forged and heat treated for durability and rated Grade 70 with a 5,400 lb working load limit per cluster. That rating reflects industry-standard strength for many light- to medium-duty towing tasks when used within the proper application and inspected regularly.

• Grade 70 alloy steel construction
• 5,400 lb working load limit per cluster hook
• Forged and heat treated for added toughness
• Designed for vehicle-frame towing and hauling scenarios

Which vehicles and towing setups are these hooks compatible with?

• Car haulers and rollback transport trailers

• Utility and fleet vehicles that tow varied loads
• Situations needing quick hook interchangeability
