Isizukulwane sakamuva sesitayela sezimboni esingu-1/4inch, 3/8inch kanye ne-1/2inch drive ratchets kusukela ku-Teng Tools enamazinyo angu-72 ukunikeza ukukhuphuka okungu-5deg phakathi kokuchofoza ukuze ufinyelele kahle ezindaweni ezivaliwe. Idizayini encane ehlangene nokubamba kwezinto ezimbili, ukukhishwa okusheshayo (ngezinguqulo zedrayivu ezingu-3/8inch kanye no-1/2inch) kanye ne-twist reverse konke kuhlanganiswe ukuze wenze ukunethezeka ukusebenzisa i-ratchet.
