||Install three wire outdoor light fixtures anywhere outside with Arlington's Gard-N-Post. The 19.5" support is made of black UV rated plastic for a long outdoor life. The color will not chip off, since the color permeates the whole post. It comes with a 3/4" NPT threaded opening on top with a 1/2" reducing bushing installed for installing a wide variety of light fixtures. The base of the Gard-N-Post has four built-in stabilizers, as well as an angled base for easy underground wiring access. There is also an installed cover to access the fixture wire easily.
