Marty Woll (N6VI) made a bunch of brackets that do this, as well (for all I
know, the same basic design). It's basically a hinge with a removable pin.
Here are some pictures of the widget in use at the JPL/CalTech Field day
All the FD pictures (look down a ways)

http://www.luxfamily.com/events/fd2004/images/P6250057.JPG is the full res
image
http://www.luxfamily.com/events/fd2004/images/P6250057x.JPG (should be a
smaller version)
There's also some photos of the same kind of hinge on the GOTA station's
tower and showing it keeping the beam flat as the tower is tilted up.
