The 1690/1790 Series narrow stile touch bar exit devices provide safe and reliable egress that is ideal for aluminum doors. Both series are certified ANSI/BHMA A156.3 Grade 1 products and boast a 10-year limited warranty. The 1690 Series design is ideal for demanding, moderate-traffic applications. The vertical rods and latch mechanisms are concealed in the vertical door stile, ensuring ideal operation. Cast metal cover plates and end caps hold up to rigorous use. A quick, single-point dogging feature in the housing deactivates the device, permitting unrestricted traffic flow. The 1690 Series may also be used to retrofit a 1990 Series crossbar device.
