Product Features

• 
  • Spring loaded ratchet mechanism minimizes operator fatigue by allowing the ring to be compressed or expanded through gradual moves and then locks at the desired size without continued pressure on the handles, heavy and large rings are safely and easily controlled
  • Replaceable tips in 0, 45 and 90 deg make it possible to remove and install rings in most applications
  • Proto® spline tools are designed to service high tensile strength fasteners used widely on military and commercial aircraft and in heavy machinery applications where vibration is prevalent
  • They are also used in automotive and industrial areas where high performance torque needs to be achieved
  • Minimizes operator fatigue
  • Locks at any position
  • 3-1/16 to 6 in Dia bore
