Product Description

Too often, we rush to get to the fire and search for victims, forgetting a fundamental technique-chocking the door. If the door is unchocked, the resulting difficulty in advancing hose through it can seriously impede initial operations. Hoses may catch on the door, preventing advancement, or catch under the door, limiting water flow. Chocking the door is one of the most effective ways to ensure an effective stretch.
