About This Product

GEARWRENCH created the original forged ratcheting wrench in 1995 and we've continued to innovate ever since. The XL Flex GearBox Ratcheting Wrenches have a flexing 72 tooth ratcheting end and a static 12 point box end. The longer beam provides great access in tight work spaces.


  • 72-tooth ratcheting box end needs a minimal 5° to move fasteners vs. 30° for standard wrenches
  • Off-corner loading design on box ends provide better grip and reduces fastener rounding
  • Longer beam provides greater access to confined work areas vs. standard length wrenches
  • Flexible head provides access to hard-to-reach bolts and fasteners
  • Size conveniently stamped on both ends of the beam for quick identification
  • Manufactured from alloy steel for better strength and longer tool life
  • Bright, full polish chrome finish easily wipes clean and resists rust and corrosion
