Extension rods yog tsim los ntawm hollow laum steels;muaj ob daim ntawv txuas ntxiv, hom puag ncig thiab hom hexagonal.Lub qhov hollow no feem ntau hu ua lub qhov dej ntws tawm, siv rau kev xa dej lossis cua thaum lub sijhawm drilling.Thiab cov xov yuav siv tau rau kev sib txuas ntawm cov couplings, shanks, couplings lossis cov khoom.
Feem ntau rau cov pas nrig txuas ntxiv, muaj R22, R25, R28, R32, R38, T38, T45, T51, ST58, T60 threads, thiab qhov sib txawv ntawm cov rods yog muaj los ntawm 600mm mus rau 6400mm feem ntau.
