The Series 670 Hopper is attractive and unique in that it perfectly complements those areas where there is limited space for a window to extend to the outside. This window hinges on the bottom and opens inward from the top. The Hopper provides airflow and security when installed as a transom above doors. Wind-blown dust and debris is reduced when compared to venting sidelites, preserving ventilation all while the door remains securely locked.
