The versatility and affordability of our vent prop offers a wide variety of quality training evolutions. This affordable prop has, specifically, been designed to give firefighters valuable hands-on training, while remaining in service at their assigned stations. With the use of this prop, fire departments are able to conduct realistic training scenarios and simulations of cutting ventilation holes in a safe and controlled environment, using a heavy duty, rugged and self-contained tool. These props are ideal for individual department training or can be shared by multiple departments. The roof prop simulates different roof pitches, and is multi locational and functional; can be placed on a drill tower, flat wall, or in a parking lot. The replacement of rafters can be done quickly without removing the top plywood or shingles with 8in on center spacing.
