Modular truss components. 1-½, 2-½, 4-½, and 8-½ sections. Models included for end cap (½") and 60° truss rotator. 

These work well in compression, but not for suspended weight. 

Ideal for light objects: Lights, small cameras, small speakers, climbing plants…

I've successfully installed one in a window to elevate some lights near the ceiling.

I use a Hex standoff (½ thread x ¾ hex) and bolt to make final height adjustments and compress the stack.
