A 4 post frame made up of pressure treated 4x4's can be used without a garage in the same way with a pully system.Farflung said:My dad and I made a pulley arrangement for our garage that lifted a 100 lb. aluminum boat up against the joists above the car. When you wanted the boat, you just lowered it onto the cars rack. If you can clear your garage door with your cap on, the same arrangement should work for a cap. Makes it a one person operation.
