If you install Hi-Loks, you need this kit! The Liberator Roller Clutch Ratchet Kit was designed by an aircraft sheet metal mechanic to enable the easy installation of Hi-Lok® fasteners in the most unusual and awkward situations. The 13 piece kit contains two roller clutch ratchet heads which are torque rated up to 80 in-lbs; two 1/4" drive studs for use with any brand of 1/4' drive socket, as well as a variety for straight and 90 degree handles. The entire system is interchangeable and will lock into an unlimited range of straight and offset configurations! The ratchet heads feature the unique ability to be "indexed" in any position by a full 360 degrees. Unit is reversible by removing the 1/4" drive stud from the ratchet head and installing it from the other side. This is one of the most flexible and adaptable tool kits you can have in your tool box! All components are manufactured from 4140 tool steel with a black oxide finish. Includes molded plastic case. 2 lbs (1Kg) shipping weight.
