Strong™ Cathedral Ceiling Adapter for Ceiling Mounts with 1-1/2 in. NPT Threading (White)
The SM-CEILING-CA is life-saver when it comes to cathedral or sloped ceilings. No more having to build a custom box to get a plum mount.
Universal Fit: With 11.5 threads per inch, this cathedral ceiling adapter will work any poles that uses a 1.5" NPT schedule 40 interface.
Slopey: It's either the eighth dwarf or a description of the ceiling you are trying to install to. Utilize the SM-CEILING-CA, and the latter won't be an issue. Pivoting up to 90 degrees, you're sure to mount the TV or projector plum to the screen.
Locking: Includes set screws to lock down the pipe's rotation so you can set it and forget it.
