Idiphu eshushu kwalenza iindawo olungisiweyo(iindawo ezihleliweyo ezifakwe ngaphakathi) zizinto ezifakwe ngaphambili (zingcwatywa) kwimisebenzi efihliweyo. Ziyinxalenye kunye nokufakwa okubekwa ngexesha lokuphosa ulwakhiwo kwaye zisetyenziselwa ukugqagqana xa kubekwa ulwakhiwo olukhulu. Emva konyango olushushu lokwenza umphezulu, ifuthe le-antirust liyaphunyezwa. Ukulungiselela ukufakwa kunye nokulungiswa kwesiseko sezixhobo zobunjineli bangaphandle. Uninzi lwezinto ezifakwe ngaphakathi zenziwe ngetsimbi. Kulwakhiwo, iibholiti zingeniswe kulwakhiwo ngaxeshanye, kwaye imisonto ye-bolt ebekwe ecaleni kwinxalenye ephezulu isetyenziselwa ukulungisa izinto kunye nokudlala indima ekunxibelelaneni nasekulungiseni. Kuqhelekile ukugcina iibholiti zezixhobo. Ngokwemizobo yokulungiswa kwemilinganiselo yokuma kwendawo yenkxaso ye-bracket-put bolts, iinxalenye ezifakwe ngaphakathi kunye nokubuyela umva kwethutyana kwaye ekugqibeleni kulungiswe.
