source for pole clamps?

[rebelwireless]

Anyone have a source for pole clamps like the ones in this auction? or more like the 'variable' toothed ones like ubiquiti ships with sectors?

Can't find anything here. They have the bent plate style of pipe-to-pipe clamps, but I just want the type that ubiquiti ships with sectors, or NB/NBE. I wan't to make a number of custom stand-offs and these are the only thing that I can't find locally or fabricate well.
