This mounting bracket is made to fit the hole on the top of a shipping container. The coupling that is on the bracket is for you to screw your desired length pole into (  Pipe NOT INCLUDED ) is 1 1/2" NPT (national pipe thread) . So anything that has these type of threads with screw into it. We do not supply pipe do the to fact of so many custom applications. The bolt used to tighten both pieces together is 15/16 ".  I recommend using a deep well socket to reach into the coupling during install. Bracket body is made from 1/4" plate steel all pieces are hand welded. Installation is a breeze shouldn't take longer then 2 minutes. Comes in RED or BLACK

 I use them for mounting my solar powered security cameras. easy to mount and very versatile.

If you any questions please contact me. Thanks
