The fastener includes a first fastener member adjustably fastened to the building frame and a second fastener member adjustably attached to the first fastener member and having a slot and a bearing element. The curtain wall units include confronting vertical frame members with brackets fastened thereto, respectively. One of the brackets has an arm engaging in the slot and the other bracket also has an arm movably supported on the bearing element.
