Clamping Flashguns to Posts/Rigging etc

When I want to clamp my hot-shoe flash someplace other than on a stand I use an Impact superclamp with an Impact hot-shoe umbrella bracket.  The clamp works well and is super strong and reliable.  The umbrella bracket gives me all the flexibility I need for aiming the flash.  I use RF triggering.
