(OPEN POSITION)            (LOCKED POSITION)

Quote:
A well oiled hinge (the smaller the better) mounted to the top of a guillotine style door on a block to impede the hinge from going beyond 180º weighted on the free edge with in my  case sinkers from my tackle box.
 
This allow the hinge to rest in the open position with gravity's help..
OUTSIDE the door raised by a predator the hinge in the 180º position(___) comes in contact with a cross member above the door.

 

INSIDE the door raised by a string the hinge in the 90º position (_l) clears the cross member above the door.
