Rich, I lift my fish trap into the rafters with an old boat winch. I spooled it with 3/8 rope, ran the rope through a series of pulleys and tied a snap connector on the rope. I made a sling out of two shorter pieces of rope that loop under the rim of the shanty and clip into the snap connector. Once it's in the rafters I leave it suspended by the rope to make it harder for mice to colonize it. Used to do it your way but came to my senses.
