The 179 Series Latching Panic
Saddle Threshold has a 5" width and allows for a 1/2" door clearance.
It's designed to protect against sound, air infiltration, wind, and
debris and is compatible with surface-applied vertical rod exit devices,
while also acting as a door stop and seal. It includes an integrated
gasket offering ThermoSeal (T), Eco-V (V), and Pile Brush (P) options.
This threshold is sound, air infiltration tested, fire rated, and BHMA
certified.
