Mounting Instructions

Stacklight bases may be mounted without the use of an extension tube or mounting base. If additional height is required, choose 0.8–30 in (20–760 mm) extension tubes that fit between the mounting base and stacklight base. The extension tubes are threaded with 3/4 in NPT threads, allowing for direct connection to conduit fittings or threaded holes without the use of a mounting base.
