The "Trough framing combo bracket" is a very clever ground anchor that is great for building hydroponic troughs.  It is designed for setting up hoops while holding together an aquaponic trough.  The trough bracket is made of high quality American made 16 gage galvanized steel.   The smart and durable engineering structure is strong enough to penetrate the earth while being rust resistant. The grounding bracket is super easy to use.  This simple and smart bracket makes building a hydroponic trough system with a hoop frame so simple as one part gets the job done.  

Simply, tap in the Trough framing combo bracket and fasten in the border with the screws provided.  If you are stretching a frame or cover, insert the PVC post right into the bracket.
