Dam Easy Residential Flood Barriers are a ready-to-use flood barrier for doors that are easy to install and deploy before a storm. There is no need for damaging hardware, adhesives or permanent fixtures when using Dam Easy - simply place between the entryway, extend the sides to fit the opening, and inflate the built-in tube until the area is completely sealed. This simple solution replaces the time, energy, and mess associated with sandbags and can be installed in under 5 minutes. One flood panel covers a door or window opening between 30.7 inches and 43.3 inches, and provides flood protection for your home or business up to 28 inches high.
