Uruzitiro, nanone rwitwa fender, ni isahani yumubiri yo hanze itwikiriye ibiziga. Ukurikije imyanya yo kwishyiriraho, igabanijwemo ibibabi byimbere hamwe nibibabi byinyuma. Uruhare rwarwo ni ugukoresha ubukanishi bwamazi kugirango ugabanye coefficient yumuyaga kandi utume imodoka ikora neza.
Itunganijwe hejuru yibiziga byikinyabiziga nka plaque yinyuma yuruhande rwikinyabiziga kandi ikorwa na resin, naho uruzitiro rugizwe nigice cyapa cyo hanze naho igice 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. Muri icyo gihe, hagati yuruhande rwigice cyisahani yinyuma nigice cyongera imbaraga, igice gihuye gishyirwaho kugirango gihuze igice cyegeranye
