Uruzitiro, nanone rwitwa fender, ni isahani yumubiri yo hanze itwikiriye ibiziga.Ukurikije aho ushyira, igabanijwemo ibibabi byimbere hamwe nibibabi byinyuma.Uruhare rwarwo ni ugukoresha ubukanishi bwamazi kugirango ugabanye coefficente yumuyaga kandi imodoka ikore neza.
Itunganijwe hejuru yibiziga byikinyabiziga nka plaque yinyuma yuruhande rwikinyabiziga kandi ikorwa na resin, naho uruzitiro rugizwe nigice cyinyuma cyinyuma hamwe nigice gishimangira resin.
Igice cya plaque yo hanze cyerekanwe kuruhande rwikinyabiziga, naho igice gishimangira kigera kumurongo wigice cyicyapa cyo hanze cyateguwe imbere mugice cyegeranye cyigice cyegeranye cyigice cyinyuma.Mugihe kimwe, hagati yigice cyuruhande rwicyapa cyo hanze nigice cyongerera imbaraga, igice gihuye gishyirwaho kugirango gihuze igice cyegeranye
