Our vents are constructed out of 4″ square 10 gauge steel tubing with expanded metal welded inside the outside end of the vent. Our units are composed of two vents, placed on opposing corners, to deliver maximum cross ventilation. They are turned at two different angles to slow the velocity of any small “pea-sized” debris that might make it through the steel grates. This will deflect them several times and slow them to a speed that won’t cause injury to the occupants.


Many of our competitors use standard aluminum roof turbines. These can be compromised single handedly with a broom handle. This is the first thing to go in a storm leaving a gaping hole in the top of the unit. This allows debris a direct path into the unit and can result in serious injury and in some cases even death.
