The Subterranean riser is specifically designed to be buried deep into the soil and features: anti rotation fins, a parachute style base and a large knurled clutch nut. This allows for secure and discreet installation of even our heaviest luminaires with up to 18” of vertical extension. The STR is a proactive solution for proper luminaire mounting height, as the landscape matures around it.
- Fully or Semi Buried Extendable Riser
