Designed as an alternative to the coro caps for the Boscoyo Studios chromatubes to be a bit more sturdy and also offer additional mounting options.
This cap offers a ring on top to allow for mounting a 6" plastic globe, in particular ones from Superior Lighting(link can be found below) with a 3.25" opening. The top mounting ring has brass threaded inserts for adding 2 screws to keep the globe in place. (drilling into the lip of the globe will be required)
The cap also has mounting holes to house up to (6) 12mm bullet node pixels to illuminate the globe.
Designed to fit onto 1/2" emt conduit
