Arlington Gard-N-Post™ GPX18BR Optional Extender, 18 in H x 4 in W, Plastic

Arlington's Gard-N-Posts™ are the attractive, safe and easy way to install light fixtures and devices outdoors! Made of non-metallic, heavy-duty plastic, our damage-resistant Gard-N-Post holds up against abuse from lawn maintenance equipment. Most have built-in stabilizers that deliver rigid support and require no assembly. The angle-cut at the bottom allows for easy access to underground wires. Some styles come with a metal grounding bushing in place, ready for the installation of an NPT fixture. And some have KOs that make them UL Listed enclosures.
