This is a 12" long steel rod with 1" of 2-56 threading on one end.
A Great Planes nylon clevis is then threaded onto the rod.
This clevis snaps to close with the added advantage of a hex-shaped shank to
allow a wrench to be used to screw the clevis on and off the rod.
Two 12" rods
Two nylon clevises
5/32" hex wrench for the clevises
