 Our Beaver guard is an optional attachment that can be easily installed in just minutes on any of our Flash Board Risers or Screw Gates. It is particularly designed to keep out pesky beavers who try to clog up your culverts! The Beaver Guard also offers protection from natures own obstacles, such as trash that may also clog up your culverts causing the water flow to be restricted. 

Please keep in mind that the Beaver Guards are 

size specific
