Nangona isando sokhuseleko sincinci, sinokudlala indima ebaluleke kakhulu kwixesha eliphambili.Kwimeko yengozi kwisithuthi, imoto ikwimeko evaliweyo, phantsi kwempembelelo enamandla, i-twist yocango ayikwazi ukuvulwa, ukusetyenziswa kwesando sokukhusela ukuphula iglasi yefestile, kunokunceda abagibeli babaleke, isando sokhuseleko eli xesha ngokwenene "isando esisindisa ubomi".
Ihamile esindisa ubomi, eyaziwa ngokuba yihamile yokhuseleko, sisixhobo esincedisayo sokubaleka esifakwe kwikhabhinethi evaliweyo.Ngokuqhelekileyo ifakwe kwiikhabhinethi ezivaliweyo ezifana neemoto apho kulula ukubaleka.Kwimeko engxamisekileyo efana nomlilo kwikhabhinethi evaliweyo efana nemoto okanye ukuwela emanzini, kulula ukususa kunye nokuqhekeza iingcango zefestile zeglasi ukuze ubaleke kakuhle.
Isando sokhuseleko ikakhulu sisebenzisa incam yeconical yesando esisindisa ubomi, kuba indawo yokunxibelelana yencam incinci, ngoko ke xa iglasi isaphulwe ngehamile, uxinzelelo lwendawo yokunxibelelana kwiglasi inkulu kakhulu (eyiyo. into efana nomgaqo we-pushpin), kwaye iglasi yemoto ixhomekeke kumandla amakhulu angaphandle ngelo xesha kunye nokuqhekeka okuncinci kwenzeka.Kwiglasi epholileyo, ukuqhekeka okuncinci kuthetha ukuba ukuhanjiswa koxinzelelo ngaphakathi kwiglasi yonke yonakele, okukhokelela ekuqhekekeni kwewebhu yesigcawu ngephanyazo, ngeli xesha, ukuba nje isando sityunyuzwe ngobunono amaxesha ambalwa, amaqhekeza eglasi isusiwe.
