Heavy-Duty Reinforced Knuckle Design
The breaker bar features a robust reinforced head and knuckle arrangement designed to withstand considerably higher loads than many conventional breaker bar designs.
This heavy-duty construction makes it particularly suitable for applications where substantial torque may be required, such as loosening stubborn wheel nuts, suspension bolts, hub fasteners, crankshaft bolts and other heavily tightened fixings.
Maximum Torque Rating of 1862Nm
With a maximum torque rating of 1862Nm, this heavy-duty 1/2" drive breaker bar is engineered for demanding high-torque applications.
The combination of the reinforced head construction and long handle provides the strength and leverage required for professional workshop environments where smaller ratchets and shorter breaker bars may not be sufficient.
750mm Extra-Long Handle for Increased Leverage
At 750mm long, the extended handle provides considerably greater leverage than a standard-length breaker bar.
Greater leverage means more torque can be applied with less physical effort, making it easier to release seized, corroded or heavily tightened fasteners.
Flexible Head for Improved Access
The hinged knuckle allows the socket angle to be adjusted relative to the handle. This can improve positioning and accessibility when working around suspension components, engine bays, wheel assemblies and other restricted areas.
Chrome Vanadium Steel Construction
Manufactured from premium-quality Chrome Vanadium steel, the breaker bar provides the strength, durability and wear resistance required for regular professional use.
The polished finish also provides additional protection against corrosion while making the tool easier to keep clean in busy workshop environments.
