FRC0330, back in '05 and I think in '00.

Both were used as latches, and as I recall the one from '00 had some assistance from a spring. (Used to lock a winch with a pin--might have been replaced by a short-throw cylinder.) The one in '05 was rigged to drop a thin sheet of Lexan. Why a thin sheet of Lexan, you ask? It's really nice to be able to deny someone who is trying to jam you against a goal half of their traction. There was no retract mechanism, though.
