Both lifts use the same rope brake that pinches the line on every pull, and both mount along or across the joists. The two hoists may arrive in separate boxes.
You will work overhead or at the top of a stud wall, so set the ladder on a level floor, face it and keep a hand on it while you drive the screws. Fasten the brackets into solid framing (a joist, a rafter or a stud), never into drywall alone, and read the instructions in the box first.
