Gûzên yekane yên ducar têne sêwirandin ku du zincîreyên zincîreyên bi tîpa yek-zincî bimeşînin, ev e ku navê "duble single" jê hatî. Bi gelemperî ev çîpek şêwazek in, lê hem şêwaza taper û hem jî şêwaza QD wekî daxwaziya xerîdar têne hilberandin. Gûzên meyên yekane yên ducar bi diranên hişk têne çêkirin û ji bo performansa bilind û berxwedanek sivik a korozyonê xwedan rengek orjînal an oksîdê reş in. Mezinahiyên stokên çîpên yekane yên ducar ji ANSI #40 - #80/DIN06B-16B diguhere lê li gorî daxwazê pîvanên din dikarin bêne çêkirin. Tiştek girîng a ku were zanîn ev e ku her çend ev çîpên çîpên ducar bin jî ew ê zincîra gerokê ducar nekin.
