BROCK® Gravity Roof Vents

Gravity Roof Ventilators
Brock offers two styles of gravity roof ventilators to help provide free air movement into the bin:

  • Elbow-style roof vent
  • Round mushroom-style roof vent

Elbow-Style Vent
The Brock elbow-style roof vent offers 190 square inches (1225 square centimeters) of ventilation opening.

Round Mushroom-Style Vent
The round mushroom-style vent from Brock provides 180 square inches (1160 square centimeters) of opening. This type of roof vent provides air circulation no matter which way the wind is blowing.

All of Brock’s rooftop vent styles are designed to minimize the chance for leakage. Factory die-cut openings and flanges in Brock’s roof panels help to assure a weather-tight seal.

For an alternate approach to cutting holes in a roof and the chance of eventual rust, leaks and condensation dripping back onto the grain, check out Brock’s better solution: the patented BROCK® Eave-Vent System.
