Garrison Flood ControlHammerhead™ Aluminum Flood Plank & Floodgate System

SHARE
Hammerhead™ Aluminum Flood Planks are the latest innovation in floodgate technology. This system utilizes U-Channel Posts that install on each side of the desired protected area. With Hammerhead™ you gain both durable protection and subtlety with the posts being unobtrusive to the existing entryway. Our U-Channel Posts install permanently without ever needing to be removed or re-installed for protection. From there, whenever a flood threat arises, aluminum planks are easily inserted into the channel providing you with durable protection against rushing water. Hammerhead™ provides stackability with numerous aluminum planks being added. This creates a stop-log floodgate barrier that is perfect for both residential and commercial properties. Protect Entrances, Garages and Doorways From Flooding: - Perimeter Opening Protection - Doorways and Window Wells - Garages and Ramps - Basement Stairwells - Loading Docks
